In covering a distance of 30 km, Abhay takes 2 hours more than Sameer. If Abhay doubles his speed, then he would take 1 hour less then Sameer. Abhay's speed (in km/hr) is : Correct Answer 5

In these type of questions go through options to save your valuable time :
Option (A)
Abhay's speed = 5 km/hr
Abhay's time = $$\frac{30}{5}$$ = 6 hr
Sameer's time = 6 - 2 = 4 hr
Abhay's new time :
= $$\frac{30}{5 × 2}$$
= 3 hr
Hence option (A) is correct as it satisfies all the conditions.

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?

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.
Given below are two quantities named A and B. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers. Quantity A: A person who travels a certain distance to his office by his car.If he increases his speed by 8 km/hr, he takes 2 hours less time but if he drives 8 km/hr slower, he takes 4 hours more time. Find the distance of office from home. Quantity B: A person who travels a certain distance to his office by his car. If he increases his speed by 10 km/hr, he takes 1 hour less time but if he further increases his speed by 5 km/hr, he takes further 20 minutes lesser time. Find the distance of office from home.
Amit travels a certain distance with 3 bikes- A, B and C. The speed of bike C is 1 km/hour less than the speed of bike B, the speed of bike B is one less than the bike A. Amit travelled 330 km with bike A. He travelled a distance which is 120 km less than the previous distance of bike B and the distance he travelled on bike C was 60 km more than the distance he travelled at bike B. He took a total time of 81 hours to travel the entire distance on 3 bikes. Find the speed of bike A?
A takes 2 hours more than B to cover a distance of 40 km. If A doubles his speed, he takes \(1\frac{1}{2}\) hour more than B to cover 80 km. To cover a distance of 120 km, how much time (in hours) will B take travelling at his same speed?
Govt has decided to connect Tripura and Delhi via a train service which is called 'Tripura Sundari Express' Two trains are running from Tripura and Delhi towards each other. Train from Tripura in covering a distance of 60 km takes 2 hours more than that of the train from Delhi. If Tripura doubles its speed, then it would take 1 hour less than that of Delhi. Tripura train's speed is?
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?
