both questions.
will give brainilst to the right answer.

Q1: 6 miles/36 minutes

6/36=1.666 miles/minute
1.666*60=10 mph
5320/1760=3.023
3.023/20=0.151 miles/minute
0.151*60=9.068 mph
10-9.068=0.932
Grant rows 0.932 mph faster than Arianna.
Q2:
D
Twice the number of pounds of peanuts is 10 pounds. 1/3 of the number of pounds of pecans is 1.111ish
10-1.1111ish = 8.9999ish
which is at most 10.

p.s. I'm not sure about Q2, I've never done anything like it before, I'm just assuming that's the answer it wants.
