Problema Solution
On a mothers 25mile commute to work, she drops her daughter off at a child care center. The first part of the trip is 7 miles less than the second part. How long is each part of her morning commute
Answer provided by our tutors
let
x = the miles passed in the first part
y = the miles passed in the second part
the first part of the trip is 7 miles less than the second part:
x = y - 7
the total length of the trip is 25 miles:
x + y = 25
by solving the system of equations:
x = y - 7
x + y = 25
we find:
x = 9 mi
y = 16 mi
