Car A travels with a speed of 50 km/hr for first hour, 60 km/hr for second hour and 70 km/hr for third hour. Car B travels with 70 km/hr in first hour, 40 km/hr in second hour and 70 km/hr in third hour. After how much time they will meet, if they both start at the same time?

Car A starts its journey from P to Q simultaneously another car Y starts from point Q to P and both reach their destination in 3 hours. Car A travels with a speed of 50 km/hr for first hour, 60 km/hr for second hour and 70 km/hr for third hour. Car B travels with 70 km/hr in first hour, 40 km/hr in second hour and 70 km/hr in third hour. After how much time they will meet, if they both start at the same time? Correct Answer 1 hour 36 min

Total distance = 50 + 60 + 70 = 180 km

In first hour, they both covered distance = 50 + 70 = 120 km

Remaining distance = 180 - 120 = 60

Time required to complete the remaining distance = × 60 = 36 mins

They will meet after 1 hour 36 minutes

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.
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’?

The question below is followed by three statements I, II, and III. You have to determine whether the data given is sufficient for answering the question. You should use the data and your knowledge of mathematics to choose the best possible answer. A car travels from city P to city Q in T hours with a speed of v km per hour. Distance between cities P and Q is D kilometers. If it increases its speed by 5 kmph it saves some time. Find the actual speed of the car. Statement I: If the car travels from P to Q with its actual speed of v kmph and come back with the speed of v + 5 kmph in 2T – 0.6 hrs Statement II: A bus start form Q at the same time when the car starts from P and the speed of the bus is 50% more than the speed of the car and the bus meets car after covering 60% of the distance Statement III: Distance between PQ is given by D2 – 25D + 200 = 0
