How long a train will take to travel a distance of 200 km with a speed of 60 km h^-1?

distance = 200 km; speed = 60 km h^-1

time = ?

$\text{Speed} = \dfrac{\text{distance}}{\text{time}} \\[1em] \text{60} = \dfrac{\text{200}}{\text{time}} \\[1em] \text{time} = \dfrac{\text{200}}{\text{60}} = 3\text{h } 20\text{min}$

So, time taken by train will be 3 hrs 20 minutes.
