FORMULA

d=rt often referred to as "dirt"

d stands for distance

r stands for rate

t stands for time

distance = 9 miles

rate=your figuring that out

time=1 and 1/2 for the first one and 3 for the second one.

You'll be setting up two equations since you have 1 1/2 hours and 3 hours

1 and 1/2 is the same as 3/2

SO

9=3/2x AND 9=3x
