A cargo train travels from station A to B (300 km) at a constant speed \(v_1\) km/h, stops at B for 30 minutes, then proceeds from B to C (200 km) at a speed \(v_2\) that is 20 % higher than \(v_1\). The total journey time from A to C is 7 hours.\n\n(a) Determine \(v_1\) (in km/h) to one decimal place.\n(b) The train's fuel consumption per kilometre is given by \(c = \frac{k}{v}\) litres/km, where \(k\) is a constant. If the whole journey consumes exactly 500 litres of fuel, find the value of \(k\) (in litre·km).

Answer Options

A. v1 ≈ 65.3 km/h; k ≈ 85.0 litre·km
