A van and a Lamborghini started travelling from Town H to Town J at the same time. After 2 hours, the Lamborghini reached Town J while the van covered only ⁵₇ of the journey. The speed of the Lamborghini was 24 km/h more than the speed of the van. Find the speed of the van.
Extra distance covered by the Lamborghini in 2 h
= 2 x 24
= 48 km

When the Lamborghini reached Town J:
Distance covered by the Lamborghini = 7 u
Distance covered by the van = 5 u

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

2 u = 48

1 u = 48 ÷ 2 = 24

Distance covered by the van when the Lamborghini reached Town J
= 5 u
= 5 x 24
= 120 km

Speed of the van
= 120 ÷ 2
= 60 km/h

Answer(s): 60 km/h
