This means the distance done was 300 feet. 


          SPEED ft/hr    TIME hours   DIST. feet

As Done      50            6           300

If           45                        300

The missing time for the question's condition is 300%2F45=6%262%2F3hours, which is 40 minutes more time.

The second speed is 9/10 of the first speed.

Since the distances are the same, the amount of time for the second trip is 10/9 of the speed for the first trip.

6%2A%2810%2F9%29+=+60%2F9+=+20%2F3

That is 6 2/3 hours, which is 2/3 of an hour, or 40 minutes, longer.

ANSWER: 40 minutes longer.

50 feet per hour?! Are you and a friend pushing it?
