Answer:
9.16 minutes per mile
At 10 miles, she is short of her intended rate
Step-by-step explanation:
2 hours means 60 * 2 = 120 minutes
Randy aims to run 13.1 miles in 120 minutes. So to get the rate [min/mi], we must divide total minutes by total miles:
120/13.1 = 9.16 minutes per mile
Moreover, she realized at 10 miles, she has taken 90 minutes. So her rate at that point [min/mi] is:
90/10 = 9 min/mi
Well, Randy is short of her intended rate
Answer: C
Explanation: they will never touch
F(x) = (3x+7)^2
f(1) = (3*1+7)^2 ... replace every x with 1
f(1) = (3+7)^2
f(1) = 10^2
f(1) = 100
Final Answer: 100
