A car travels at a speed of 60 km/hr and covers a particular distance in one hour. How long will it take for another car to cover the same distance at 40 km/hr ?

Distance = Speed × Time = 60 km.
Time taken at 40 kmph

=	60	=	3	hours
	40		2

Second Method :
Here, S₁ = 60, t₁ = 1
S₂ = 40, t₂ = ?
S₁t₁ = S₂t₂
60 × 1 = 40 × t₂

t₂ =	3	hours
	2
