Question

Q3.
A train is moving at a uniform speed of 75 km/h.
(a) How far will it travel in 20 minutes?
(b) Find the time required to cover a distance of 250 km.​

Answer 1

Answer:

solve a= speed = 75km/h = 75000m/60min = 1250m/min

time= 20 minutes

distance = time × speed

= 20× 1250 = 2500m or 2km5m or 2.5 km

solve b = speed = 75km/h

distance = 250 km

time = distance/ speed

= 250km / 75km/h

= 10/3 hours or 200minutes
