A car drove from Town A to Town B without stopping

A car drove from Town A to Town B without stopping. The car traveled the first 50 miles of its journey at an average speed of 25 miles per hour. What was the car’s average speed, in miles per hour, for the remaining 110 miles if the car’s average speed for the entire trip was 40 miles per hour?

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
