Answer 2

Ratio of their speed s :-

car's speed : train's speed

Car's Case

S = Distance = 72 km

T = Time = 2 hrs

∴ Speed = V = S ÷ T

= 72 ÷ 2 = 36 km/hr

Train's Case

S = Distance = 120 km

T = Time = 3 hrs

∴ Speed = V = S ÷ T

= 120 ÷ 3 = 40 km/hr

Ratio of their speed s

Car's speed to Train's speed

= 36 : 40

= 9 : 10

Ratio ⇨ 9 : 10 ⇨ car to train

HAVE A GOOD DAY :D
