Answer:
1 hour
Explanation:
MPH stands for miles per hour. So on a highway, if you were going 80MPH, you would go 80 miles, every hour. In this scenario we are going 50 MPH, it would take an hour to go 50 miles. If, however, the car was going slower, like 25mph, it would take 2 hours because 25+25 is 50.
