To stay in shape, Julie goes running three times a week. On Wednesday, she ran 4 miles less than on Monday. On Friday, she ran twice as far as she ran on Wednesday. If she ran 26 miles altogether, how far did she run on Friday?

Respuesta :

charstar
monday=m
friday=f
wednsday=w

w=m-4
f=2w
w+m+f=26

In terms of w:
w+w+4+2w=26
w+w+2w+4=26
4w+4=26
4w=22
w=5.5

f=2w
f=5.5*2
f=11

Hope this helps :)
