Question

a train travels at a speed of 180km/h . how far will it travels in 4hrs

Answer 1

Time = 4hrs
speed = 180 km/h
distance = ?

We have a formula.
S*T = D

4*180 = D
720 km = Distance

Answer 2

Well it is a really easy question :)

Speed of train = 180 km/h
Time in which distance is to be calculated = 4 hours
As we know,
Speed = Distance/Time

From this relation,
Distance = Speed * Time
Distance = 180 * 4
Distance = 720 km

Hence,
The train running at the speed of 180 km/h will cover 720 km in 4 hours.

Hope it helps!
