A bus travels 126km in 3 hours and a train travels 315 km in 5 hours. Find the ratio of their speeds.

a)2:3
b)3:2
c)1:4
d)4:1

Answer 1

Answer:

Your answer is a) 2:3

Step-by-step explanation:

speed = distance/time

speed of bus = 126 /3 km/h

                      = 42 km/h

speed of train = 315 / 5 km/h

                        = 63 km/h

ratio : 42 / 63      (divide by 3)

        = 14 / 21       (divide by 7)

        = 2 / 3

The ratio is 2:3
