Question

A bullock-cart travels 24 km in 3 hours and a train travels 120 km in 2 hours. Find the ratio fo their speeds.

Answer 1

Speed = $\frac{\mathrm{Distance}}{\mathrm{Time}\mathrm{taken}}$

Distance covered by bullock-cart = 24 km
Time taken = 3 hours
Speed of bullock-cart = $\frac{24}{3}=8\mathrm{km}/\mathrm{h}$

Distance covered by train = 120 km
Time taken = 2 hours

Speed of train = $\frac{120}{2}=60\mathrm{km}/\mathrm{h}$

Ratio for their speeds = Speed of bullock-cart : Speed of train = 8 : 60
= 2 : 15
