With what speed should a car travel so that it can cover a distance of 10 km in 5 min?

Distance= 10 km
Time = 5 min = $\frac{5}{60}$ hr = $\frac{1}{12}$ hr ($\because 1 \mathrm{hour} = 60 \min$)
Speed =$\frac{\mathrm{Distance}}{\mathrm{Time}}$

Substituting the values in the equation,

Speed= $\frac{10}{{\displaystyle \raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$12$}\right.}}$= 120 km/hr

Therefore, 120 km/hr is the correct response.
