H^2 = x^2 + y^2
where h is the hypotenuse, x and y are legs.
h^2 = 20^2 + 28^2
h^2 = 400 + 786
h^2 = 1184
h = sqrt(1184)
h = 34.4 in.
Letter C
7/12 of 1 hour:
1 hour = 60 min.
7/12 * 60
7 * 5 = 35
Francis ran 2 1/2 miles in 35 min.
2 1/2 = 5/2
5/2 miles = 35 min
x miles = 60 min
(Cross Multiply)
5/2 * 60 = 35x
5 * 30 = 35x
150 / 35 = x
x = 30 / 7 = 4 2/7 miles
Francis ran 4 2/7 miles in one hour.
The answer would be B a≈9.22
