You're basically told that Lin has traveled 20% of 75. Since 20% is one fifth, she has traveled 75/5=15 miles so far.
Your answer is 40mm
3+12+12+13
=40
So you just have to use distance formula

Answer:
wk. 1 : 104, wk. 2 : 109, wk.3 : 218
Step-by-step explanation:
x = 1st week, y = 2nd week, z = 3rd week
x + y + z = 431
y = x + 5.........y - 5 = x
z = 2y
(y - 5) + y + 2y = 431
4y - 5 = 431
4y = 431 + 5
4y = 436
y = 436/4
y = 109 <==== week 2
z = 2y
z = 2(109)
z = 218 <==== week 3
x = y - 5
x = 109 - 5
x = 104 <==== week 1
