Two planes started at the same time from two airports that are 3600 kilometers apart and flew toward each other. One plane flew at 792 kilometers and the other flew at 888 kilometers per hour. In how many hours were the planes still 240 kilometers part?

What is their combined speed approaching each other?

The two cover all but 240km of the 3600. What is that distance?

Divide the distance by the speed to find how long.

distance= rate*time

3600-240=(792+888)km/hr * time

solve for time.
