Problema Solution
Two highway paving crews are 20 miles apart, working toward each other. One crew paves 0.4 mi of road per day more than the other crew. They meet after 10 days. Find the rate at which each crew paves the road
Answer provided by our tutors
let
v = miles per day the rate at which one team paves
v + 0.4 = miles per day the rate at which the other team paves
10*v + 10(v + 0.4) = 20
by solving we find
v = 0.8 miles per day
click here to see the step by step solution of the equation
v + 0.4 = 0.8 + 0.4 = 1.2 miles per day
one crew paves at a rate of 0.8 miles per day while the other paves at a rate of 1.2 miles per day.
