Question

Two families are vacationing together, driving in separate cars. The Harris family averages 40 mph, leaving Hometown 12 minutes ahead of the Arlen family, who averages 55 mph. How long will it take the Arlen family to overtake the Harris family?

Answer 1

I believe, if I'm not correct but I think the answer would be 8 minutes or less.. Considering the fact that the Harris Family left 12 minutes ahead and the Arlen family is Averaging 55 MPH.. Too the speed that the Arlen's are going make the time for them to catch up to the harris's shorter. The Arlen's are going 15 mph faster sooo.. Yeah.. Tell em if this helps! :D

Answer 2

32

Explanation:

40(t+12/60) = 55t

40t +8 = 55t

8 = 15t

t = .533333 hr

=0.533333 X 60 = 32 min
