A bus and a Lamborghini started travelling from Town A to Town B at the same time. After 6 hours, the Lamborghini reached Town B while the bus covered only ⁷₁₀ of the journey. The speed of the Lamborghini was 24 km/h more than the speed of the bus. Find the speed of the bus.
Extra distance covered by the Lamborghini in 6 h
= 6 x 24
= 144 km

When the Lamborghini reached Town B:
Distance covered by the Lamborghini = 10 u
Distance covered by the bus = 7 u

Extra distance covered by the Lamborghini 
= 10 u - 7 u
= 3 u

3 u = 144

1 u = 144 ÷ 3 = 48

Distance covered by the bus when the Lamborghini reached Town B
= 7 u
= 7 x 48
= 336 km

Speed of the bus
= 336 ÷ 6
= 56 km/h

Answer(s): 56 km/h
