Question 1038937: brothers harry and chris walk to
school from house. the former takes 40 minutes
while the later 30 minutes. one day herry started 5
minutes earlier than chris. in how many minutes
would chris overtake herry? Answer by jorel555(1290) (Show Source):
You can put this solution on YOUR website! If harry takes 40 minutes to walk to school, then he walks 1/40 of the distance per minute. Similarly, chris walks 1/30 of the distance/minute. After n minutes,then:
n/40+5/40=n/30
n+5/40=n/30
40n=30(n+5)
10n=150
n=15 minutes before chris catches up to harry!!!!!!!!!
