Problema Solution
at 2 p.m. two cars leace eagle River, WI, one headed north and one headed south. If the car headed north averages 50 mph and the car headed south averages 60 mph, when will the cars be 165 miles apart?
Answer provided by our tutors
Let SD is distance south ND is distance north
SD = 60mph*t
ND =50mph *t
distance apart is 165 mi at time
SD+ND = 165 (must be added because distance from starting point)
60*t+50*t = 165
110*t = 165
t = 1,5h
