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?
[A] $1\ hours$
[B] $\frac{3}{2}\ hours$
[C] $2\ hours$
[D] $\frac{5}{2}\ hours$

$\mathbf{\frac{3}{2}\ hours}$
Distance = Speed $\times$ Time = 60 km
Time taken at 40 km/hr $= \frac{60}{40} = \frac{3}{2}\ hours$
Hence option [B] is correct answer.
