Answer:
x = -1
Step-by-step explanation:
f() = 120, therefore we can create this equation:
120 = 150 ÷ ( - z)
cross-multiply to get: 24 - 120z = 150
-120z = 126
z = -1

To make this a little easier, you would want to turn 3/4 into 9/12, to match 5/12's denominator.
You would then just add 7/1 to both fractions
(5/12+7/1=12/12 or 1 minutes)
(9/12+7/1=16/12=1 1/3)
So your answer would be 1.333... miles per minute
Hope this helps
