A.
the 2 quantaties are
ricky's distance and greg's distance
it should be total 8 miles
B. ricky distance=ricky rate times ricky time
ricky distance=1.5*3
ricky distance=4.5 miles
ricky distance+greg distance=8
4.5+gdistance=8
minus 4.5 both sides
gdistance=3.5
gdistance=grate time gtime
3.5=2 times time
divide both sides by 2
1.75=time
greg walked 1.75 hour
not sure how to do variable thing and what goes where
ricky walked 4.5 miles
greg walked 1.75 hour and traveled 3.5 miles
