A car and a van started from two cities at the same time and travelled towards each other at
steady speeds. The car took 4 hours to cover the distance between the two cities and the van
took 6 hours. After what amount of time did they pass each other?

1. This is just a work problem in disguise. Together the cars must cover a distance.

1/x = 1/4 + 1/6 = 5/12
x = 12/5

Check. Say the distance is 120 miles
In 2.4 hours, the car covers 2.4/4 = 0.6 the distance.
In 2.4 hours, the van covers 2.4/6 = .4 the distance. ok
