Question

A train is moving at a uniform speed of 75 km/hour.

(1) how far will it travel in 20 minutes.
(2) Find the time required to cover a distance of 250 km.

Answer 1

1.

Speed = distance ÷ time

distance = speed × time

given,

• speed =75km/h
• time= 20mins= 20/60= 1/3 h

distance = 75 × 1/3

distance = 25km

2.

Time= distance ÷ speed

given,

speed = 75km/h

distance = 250km

time = 250 ÷75

time = 1/3 h
