Question

Usha and Valsamma are running a race. Usha is running on the inner circle. Valsamma is running on the outer circle.
• Valsamma runs faster than Usha. But still she loses the race. Can you guess why? __________



• Have you seen any race where runners start from different places — like in this picture? Guess why?

Answer 1

• The starting and the ending points of the race coincide. Now, since the radius of the outer circle is greater than the radius of the inner circle, the length of the boundary of the outer circle will be greater than the length of the boundary of the inner circle. Hence, Valsamma covers more distance than Usha while taking one round of the circular track. Thus, she loses the race even if she runs faster than Usha.

• Usually circular tracks have different starting point because the radius of the track of the different runner are different.
