Question

A train covers 120 km in 2 hours.How much time is needed to cover 540 km at the same speed

Answer 1

2 hrs = 120 km

1 hrs = 60km

now 540/60

9 hrs

Answer 2

speed = distance/ time taken
=120 km/ 2 hour
= 60 km/hour

How much time is needed to cover 540 km.
so we have to find time taken.

60 = 540/time taken
time taken = 540 km/60 km/ hour
= 9 hours_ Ans
