The answer would be choice A. 2
He can go 3/5 of a mile in 1/4 of an hour. 1/2 of an hour is twice that of 1/4 of an hour
so all you have to do is double the 3/5
3/5+3/5= 6/5 or 1 1/5 miles
alternatively you can just multiply by two,
3/5*2/1=6/5 or 1 1/5 miles
<span>R = 11 - 2m
S = n + 5
T = -m - 3n + 8
R - S + T
(</span>11 - 2m) - (n + 5) + (-m - 3n + 8)
6 - 2m - n - m - 3n + 8
14 - 3m - 4n
-3m - 4n + 14
