Question

A train of length 100m is moving at a speed of 50km/h. A horse is running alongside the train at a speed of 56km/h. How long will it take the horse to overtake the train?

Answer 1

I've attached working. The method I've used explains everything, is a bit long winded but is the best way to explain :)

Answer 2

It will take 1 MINUTE for the horse to overtake the train.
(56 – 50) 6 km/hr
0.1/6 = 1/60 hr = 1 min
