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:
Each one of the ten people has to shake hands with all the $20$ other people they don’t know. So $10\cdot20 = 200$. From there, we calculate how many handshakes occurred between the people who don’t know each other. This is simply counting how many ways to choose two people to shake hands from $10$, or $\binom{10}{2} = 45$. Thus the answer is $200 + 45 = \boxed{\textbf{(B)}\ 245}$.
