Time & Distance
A car cover a distance of 330 km in a certain amount of time at speed of 55 km/h. What is the average speed of bike that cover distance of 15 km less than car in 1 hour less than time taken by car?
|E||None of these|
Time taken by car = 330 /35 = 6 hours
Time taken by bike = 6 – 1 = 5 hours
So, speed of bike = km/h
