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.

Step-by-step explanation:o
x + y = 10........(1)
x - y = 14..........(2)
Adding (1) and (2)
2x = 24
x = 24/2
x = 12
And x + y = 10.......(1)
12 + y = 10
y = 10 - 12
y = -2
The number are 12 and -2
