Question

Harry took 4 h to travel from A to B. Danny took 6 h to travel from B to A. When they met, they were 1.2km away from the midpoint. What was the distance between A and B?

Answer

A ——————— 1u ——————– mid-point ——- 1.2 km ——- (1u – 1.2) km ——- B
(1u + 1.2) x 4 = 4u + 4.8 = (1u – 1.2) x 6 = 6u – 7.2
2u = 12

Ans : 12 km.
