SOLUTION: A family drove from home to Truckee at 55 mph and returned the same route at 40 mph due to a snowstorm. The total travel time was 4.75 hours. Determine the distance between thei

Let L be one way distanse, in miles.


Then the"time equation" is


 +  =       hours.


Multiply by 55*8 both sides:


8L + 11L = 2090  ====>  19L = 2090  ====>  L =  = 110.


Answer.  One way distance was 110 miles.


Check.   Checking is a necessary part of the solution.
