You can put this solution on YOUR website! There are 60 minutes in one hour, 20 minutes being one third of it.
So we can multiply both the miles and minutes in the problem to reach our solution.
50 miles in 20 minutes times three equals
50 x 3 = 150 miles
20 x 3 = 60 minutes (remember 60 minutes = 1 hour)
.
Thus, the solution is 150 miles per hour.
