A car covers a distance of 500 km with an average speed of 10 km h-1. How much time does it take to cover the distance?
Given:
Total distance travelled = 500km
Average speed = 10kmhr
Calculation:
As we know,
Averagespeed(vav)=TotaldistancetravelledTotaltimetaken10kmhr=500kmTotaltimetakenTotaltimetaken=50010Totaltimetaken=50hr
Hence, the total time is 50 hr.
The maximum speed of a train is 90 km/h . It takes 10 hours to cover a distance of 500 km. Find the ratio of its average speed to maximum speed.
