A van and a Lamborghini started travelling from Town F to Town G at the same time. After 5 hours, the Lamborghini reached Town G while the van covered only ⁷₉ of the journey. The speed of the van was 24 km/h less than the speed of the Lamborghini. Find the speed of the Lamborghini.
Extra distance covered by the Lamborghini in 5 h
= 5 x 24
= 120 km

When the Lamborghini reached Town G:
Distance covered by the Lamborghini = 9 u
Distance covered by the van = 7 u

Extra distance covered by the Lamborghini 
= 9 u - 7 u
= 2 u

2 u = 120

1 u = 120 ÷ 2 = 60

Distance covered by the Lamborghini when it reached Town G
= 9 u
= 9 x 60
= 540 km

Speed of the Lamborghini
= 540 ÷ 5
= 108 km/h

Answer(s): 108 km/h
