Explanation:

Let the length of track is d metres.

AB=dd-12AC=dd-18BC=dd-8

Solving we get, d = 48 m

Hence, option (b).

Alternatively,

When A finished, the gap between B and C was 6 m. After B ran another 12 m, the gap is increased by another 2 m.

∴ A gap of 2 m is created when B runs 12 m.

∴ A gap of 8 m is created when B runs = 12 × 4 = 48 m
