A bus and a Lamborghini started travelling from Town W to Town X at the same time. After 3 hours, the Lamborghini reached Town X while the bus covered only ⁵₇ of the journey. The speed of the Lamborghini was 26 km/h more than the speed of the bus. Find the speed of the bus.
Extra distance covered by the Lamborghini in 3 h
= 3 x 26
= 78 km

When the Lamborghini reached Town X:
Distance covered by the Lamborghini = 7 u
Distance covered by the bus = 5 u

Extra distance covered by the Lamborghini 
= 7 u - 5 u
= 2 u

2 u = 78

1 u = 78 ÷ 2 = 39

Distance covered by the bus when the Lamborghini reached Town X
= 5 u
= 5 x 39
= 195 km

Speed of the bus
= 195 ÷ 3
= 65 km/h

Answer(s): 65 km/h
