Question

A train is moving at a speed of 120kmph. How far will it travel in 36 min

Answer 1

Step-by-step explanation:

20 min. = 20 min.(1)

= 20 min. (1 hr./60 min.) min. since there are 60 minutes in 1 hour.

= (20 min./60 min.)(1 hr.)

= (20/60) hr. (Note: the "minute" units cancelled out)

= (1/3) hr.

Now, substituting into the "distance-rate-time" formula for time t and for speed r to find distance d traveled, we have:

d = rt

= (120 km/hr)[(1/3) hr.]

= (120/3) km.

d = 40 km. is the distance covered by a train travelling at a constant speed or an average speed of 120 km/hr. in 20 minutes.
