Question

Mohit covers a certain distance in 6 hrs by his scooter at a speed of 40 kmh^-1.

(i) Find the time taken by Manjoor to cover the same distance by his car at the speed of 60 kmh^-1.

(ii) Find the speed of Joseph, if he takes 8 hrs to complete the same distance.

Answer 1

Mohit’s speed = 40 km/h or kmh^-1

Distance covered in = 6 hours

Distance = 40 x 6 = 240 km

(i) Manjoor car’s speed = 60 kmh^-1

He will cover the distance of 240 km in = 240/60 = 4 hours

(ii) Joseph covered that distance in 8 hours

His speed = 240/8 = 30 kmh^-1
