Alexandra went on a 42 mile trip to a soccer game. on the way back, due to road construction she had to drive 21 miles per hour slower. this made the trip take 1 hour longer. how fast did she drive to the soccer game?

Let x miles per hour be the speed Alexandra drove to the soccer game. Then she spent hours to drive to the soccer game.

On the way back, due to road construction she had to drive 21 miles per hour slower, then her speed is x-21 miles per hour and she spent hours.
