Question 987215: Ben walks at a rate of 3 miles per hour. He runs at a rate of 6 miles per hour. In one week, the combined distance that he walks and runs is 210 miles.
Write a linear model that relates the number of hours that Ben walks to the number of hours Ben runs.
Ben runs for 25 hours. For how many hours does he run? Answer by macston(5194) (Show Source):
You can put this solution on YOUR website! .
W=hours walked; R=hours ran
.
3W+6R=210
.
For R=25:
3W+6(25)=210
3W=150=210
3W=60
W=30
.
ANSWER: He walked 30 hours
