Answer: 1.8 mi.

Explanation:

Formula for distance, rate, time

d = rt >I think of dirt

x = r, rate

Trip up:

r= 45 min = .75 hr >convert by dividing by 60

d = x(.75) This is in

d = x

x = d/.75

Trip down:

r= 20 min = .333 hr

d = (x+3)(.333) >distribute

d = .333x + 1

Substitute trip up into trip down equation and solve for d

d = .333(d/.75) +1

d = .444d +1 >subtract .444d from both sides

.555d = 1 >divide .555 to both sides

d = 1.8 mi
