60 km

Explanation:

The car is travelling at the same speed so we can compare the distances with the times using direct proportion.
He will drive further in a longer time.

It makes no difference whether you use hours or minutes, because we want an answer in km.

1 hour 30 mins = 90 mins

108/90 = x/50 " "(larr " km")/(larr " min")

x = (108"km"xx50cancel"min")/(90cancel"min"

x = "60 km"
