Question

the ratio of the speeds of two vehicles is 2: 3, if the second vehicle covers 72 km in 2 hours, what is the speed of the first vehicle

Answer 1

the ratio of speed of cars =2:3
then speed of first car is 2x and second car is 3x
speed of second vehicle = 72/2 km/h
= 36 km/h
so,3x=36km/h
x=36/3=12km/h
speed of first car=2(12)=24km/h
