Question

The speed of a car is 1.5 times the speed of a bus. If the speed of the car is 60 km/hr then what will be the difference in the time taken by the bus and the time taken by the car to cover a distance of 720 km?

• A. 6 hours
• B. 8 hours
• C. 9 hours
• D. 7 hours

Answer 1

Answer:

A. 6 hours

Let the speed of bus be x km/hr.

speed of car = 1.5x = 60 km/hr

x = 60/1.5 = 40 km/hr

speed of bus = 40 km/hr

time taken by car to cover 720 km = 720/ 60 = 12 hr

Time taken by bus to cover 720 km = 720/ 40 = 18 hr

Thus, difference in the time taken by the bus and the time taken by the car to cover 720 km = (18 – 12) hr = 6 hr.
