A Bus is running at a speed of 80 km/h. After 2 hours of journey its tyre punctured and the speed decreased by 25% and the Bus reached its destination 1 hour late. If the total journey took total 3 hours due to tyre puncture, then what is the total distance covered by the Bus?

A Bus is running at a speed of 80 km/h. After 2 hours of journey its tyre punctured and the speed decreased by 25% and the Bus reached its destination 1 hour late. If the total journey took total 3 hours due to tyre puncture, then what is the total distance covered by the Bus? Correct Answer None of these

Given:

Speed of Bus = 80 km/h

Decrease in speed = 25%

Time by which Bus is late = 1 hour

Time for which Bus travelled at 80 km/h = 2 hours

Formula used:

Speed = Distance/Time

Calculations:

Decreased speed of Bus = 80 - (80 × 25%)

⇒ 80 - 20

⇒ 60 km/h

Total Distance covered = Distance covered at 80 km/h + Distance covered at 60 km/h

⇒ (80 × 2) + (60 × 1)

⇒ 160 + 60

⇒ 220 km

∴ The total distance covered by the Bus is 220 km.

Each of the question below consists of a question and three statements number I, II and III given below it. You have to decide whether the data provided in the statement are sufficient to answer the question. If the bus is travelling from Surat to Ahmadabad and a car is travelling from Ahmadabad to Surat, then what is the distance between Surat and Ahmadabad? I. The speed of a car is 40% less than the speed of bus. Bus started at 9 am and car started at 10 am and they meet at 3 pm of the same day. II. After travelling for 1 hour, because of traffic average speed of bus is decreased by 20% and covers distance between Surat to Ahmadabad in 11 hours. Original speed of car is 20% less than original speed of bus and before crossing bus it covered 200 km if starts 1 hour later than bus. After crossing car, bus covers remaining distance in 5 hours. III. Speed of bus is 10 km/hr more than the speed of car and before crossing car ratio of distances covered bus and car in same time was 5 : 4. Time taken by car to cover the distance between Ahmadabad and Surat is 2 hours 15 minutes more than time taken by bus to cover the same distance.
Each question below is followed by two statements I and II. You have to determine whether the data given in the statements are sufficient for answering the question. You should use the data and your knowledge of Mathematics to choose the best possible answer. A train started from a point P towards Q and met with an accident after traveling 30 km, the speed of train got reduced after the accident and finally reached the destination 16 min late, then what is distance covered between P and Q? I. The train would have reached 21 min late had the accident happened 10 km after P. II. The train would have reached 12 min late had the accident happened 20 km before Q
7 members A, B, C, D, E, F and G are going to office in a particular order (not necessarily in the same order). C reached the office in the end. None of them reached the office at the same time. Atleast 3 members reached the office after G. E reached the office just after A and G reached the office just after E. F reached the office just before A but didn't reached the office after D. Who among them reached the office first?
The speed of a car during the 2nd hour of its journey is thrice of that in the 1st hour. Also, its 3rd-hour speed is the average speed in the first two hours. If the car had traveled for the entire duration at the speed of 2nd-hour speed then it would have traveled 150 km more. By what percent distance covered in the first case will decrease than distance covered in the latter case in the same time i.e. 3 hours?
A bus travels 2/5 of a total journey at its usual speed. The remaining distance was covered by bus at 6/7 of its usual speed. Due to slow speed it reaches its destination 50 minutes late. If the total distance is 200 kms, then what is the usual speed (in km/hr) of bus?
After covering a distance of 180 km with a uniform speed there is some defect in train engine and therefore, its speed is reduced to 60% of its original speed. Consequently, the train reaches its destination late by 17.6 hours. Had it happened after covering 90 km more, they would have reached 16.4 hours late. Then, what is the distance is covered by the train?
A bus travels 2/5 of a total journey at its usual speed. The remaining distance was covered by bus at 6/7 of its usual speed. Due to slow speed it reachesits destination 50 minutes late. If the total distance is 200 kms, then what is the usual speed (in km/hr) of bus?
If Rati travels at his usual speed for ‘x’ hours, he covers the same distance as he covered when he travels at a speed 30 km/hr less than usual, but for (x + 3) hours. Which of the following can be determined? (A) If he travels at 20 km/hr less speed than usual, he can cover a distance of 240 km in (x - 1) hours. What is the value of ‘x’? (B) If travels at his usual speed for (t + 2) hours, and at 50% of his usual speed for (t - 2) hours, his average speed for the journey is 68 km/hr. What is his usual speed? (C) His usual speed (in km/hr) is a multiple of 5 between 40 and 50 (both inclusive). If ‘x’ is a whole number, what is his usual speed? (D) If he travels at his usual speed for ‘t’ hours, he covers a distance of 400 km. What is the value of ‘x’?
A bus covered a certain distance from village A to village B at the speed of 60 km/hr. However on its return journey it got stuck in traffic and covered the same distance at the speed of 40 km/hr and took 2 hours more to reach its destination. What is the distance covered between villages A and B ?
