Answer:
Your answer is B
Step-by-step explanation:
There are 3 kids ages 9-10, so that's the first 3.
There are 10 kids ages 10-11, so that's the second 10.
There are 6 kids ages 11-12, so that's the third 6.
add those kids up and you get 19
the answer is 32 because you add 9 plus 7 then you multiply tha th # by 2
Running 2 miles at 8:15 per mile takes 16:30 minutes.
Running 3 miles at 7:12 per mile takes 21:36 minutes.
The total running time is 16:30 + 21:36 = 38:06 minutes. That length of time after 6:52 am is 7:30:06 am.
You get home for breakfast at 6 seconds past 7:30 am.
