Word speed problem

Two trains are moving towards each other, each traveling 75 mph. When the trains are 500 miles
apart, a hawk starts flying back and forth between them (as soon as it gets to one train it turns around
and flies back to the other). If the hawk can fly at a speed of 90 mph how far will the hawk have
flown when the trains meet?

Thanks.

Hi alikn;

500 / 150 * 90 = 300 miles the hawk flies.

This is a classic (very old) problem ... with a surprisingly simple answer.
