In a 100 m race, A beats B by 10 m and C by 13 m. In a race of 180 m, B will beat C by:

1. 5.4 m
2. 4.5 m
3. 5 m
4. 6 m

Correct answer: 6 m

Solution

From the 100 m race, when A runs 100 m, B runs 90 m and C runs 87 m. So \(B:C=90:87=30:29\). Therefore, when B runs 180 m, C runs \(180\times \frac{29}{30}=174\) m, so B beats C by 6 m.
