Two cars start 150 km apart and drive towards each other, one at 60 km/h and the other at 40 km/h. After how many hours will they meet?
Correct answer E. 1.5
Explanation
Moving towards each other, the cars close the gap at their combined speed of 100 km/h, so the 150 km separation disappears in 150 ÷ 100 = 1.5 hours.
