A bus and a Lamborghini started travelling from Town U to Town V at the same time. After 3 hours, the Lamborghini reached Town V while the bus covered only ⁷₁₀ of the journey. The speed of the bus was 24 km/h less than the speed of the Lamborghini. Find the speed of the Lamborghini.
Extra distance covered by the Lamborghini in 3 h
= 3 x 24
= 72 km

When the Lamborghini reached Town V:
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 = 72

1 u = 72 ÷ 3 = 24

Distance covered by the Lamborghini when it reached Town V
= 10 u
= 10 x 24
= 240 km

Speed of the Lamborghini
= 240 ÷ 3
= 80 km/h

Answer(s): 80 km/h
