Question

A train moves at a speed 72km/hr. When it approaches the station the driver brakes the train stops in 30 minutes.
a) what is the value of deceleration?
b) what is the duration it takes to stop?

Answer 1

Are you sure you copied that question correctly? It should not take 30 minutes to stop a train.

Why are they asking you the duration of stopping if they already told you it is 30 minutes?

Answer 2

I have no idea that is why i asked :/
