Question
Answer
Sorry, realised a careless mistake on my end. The time starts from 8.30am instead of 8am.
So from 8.30M to 9.10am, its 40mins or 2/3 hr.
Distance by Ah Meng: 60 × 2/3 = 40km
Distance by Beng Hwee: 93 × 2/3 = 62km
Distance of return journey: (62 – 40) ÷ 2 = 11km
Distance from Town X to Town Y: 11 + 40 = 51km
