A train covers a distance of 456 km in 4hours 45 minutes. Calculate the speed of the train.

By definition we have to:

v = d / t

Where,

v: speed

d: distance

t: time

The time in hours is given by:

t = 4 + (45/60)

t = 4.75 hours

Substituting values we have:

v = 456 / 4.75

v = 96 km / h

Answer:

the speed of the train is:

v = 96 km / h
