Action Man ran 22 mph, and Ed's dog followed behind, running 11 mph. If the dog took 7.5 minutes longer than Action Man to get there, how far away was the hospital?
Dog and man ran the same dist. write a dist equation:
Change 7.5 min to 7.5/60 = .125 hrs
Let t = Man's running time,
(t+.125) = dog's running time
22t = 11(t+.125)
22t = 11t + 1.375
22t - 11t = 1.375
11t = 1.375
t = .125 hrs
Dist = 22 * .125 = 2.75 mi to hospital
