Problema Solution
May drives 32 miles to chicago during a snow storm at a certain speed. She returns after the storm 10 MPH faster. Total time for the round trip is 1 hour.what is her speed in EACH direction?
Answer provided by our tutors
in direct way speed =x
returning speed =10+x
16/x+16/(10+x)=1
160+32x=x(10+x)
x^2-22x-160=0
x=11.52 mile/hr
returning speed =22.52 mile /hr
