Answer: 78
Step-by-step explanation: Remember every triangle ads up to a total of 180 degrees. You just have to make sure that it adds up to 180
(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
change to improper fraction:
22 4/5
22*5=110+4=114
114/5
divide:
114/5=22.8
Thus, 22 4/5 as a decimal is 22.8
Sq.root of 1240 is approx 35 mm
