(1 / 5) hour is 12 minutes and five times this equals 1 hour.
So the distance times 5 equals miles per hour.
(3 / 4) * 5 = 15 / 4 = 3.75 mph
1 is 52 2 is 30 3 is 30 4 is 62 5 is 118
The scale factor is 4 and for the perimeter just use the distance formula
The answer you are looking for is 12.0
62 triangle a and 59 triangle b
