Question 950259

Jane leaves her house and drives in a straight line at a speed of 55 mph. Her speed on the return trip is 65 mph.

Let x = Distance of her trip

The trip back home takes 13 minutes less than the outbound trip

   Time for outbound = x/55
   Time for return trip = x/65

 equation :  x/55-x/65=13/60
             x=1859/24   or   77.46
Jane's total travel time in hours = 1859/(24*55) + 1859/(24*55)  = 169/60  hours  or  169 minutes
