Question

A car running at 65 mph taking 1hr to cover a distance if the speed is reduced by 15 kmph then in how much time will cover the distance

Answer 1

First determine the distance. Its traveling at 65 for an hour so:

(65 km/h) *1h = 65 km

Divide the same distance by the new speed (65–15) to get time.

65km/(65–15)km/hour = 1.3 hours
