Question 650622
two cars travel the same route to a town that is 200 miles from where they
 started and then return, by the same route to where they started.
 Car A averages 50 miles per hour one way and 40 miles per hour on the return trip.
 Car B averages 45 miles per hour both ways.
 Do the cars travel the total distance in the same amount of time?
:
Car A time
A = {{{200/50}}} + {{{200/40}}}
A = 9 hrs
:
Car B time
B = {{{400/45}}}
B = 8.89 hrs
