If a racing car covers 500 km in 4 hours then find its speed.
125 km/h
25 km/h
250 km/h
100 km/h
Given, distance covered by racing car = 500 km
Time took to cover 500 km = 4 h
∵ Speed = distancetime
⇒ speed of car = 5004
= 125 km/h
A race boat covers a distance of 60km downstream in one and a half hour. It covers this distance upstream in 2 hours. The speed of the race boat in still water is 35km/hr. Find the speed of the steam.
