Question 318312
On a road trip they drove 55 miles per hour to California, on the way home they drove 65 miles per hour.
 How many miles did they drive on the way to California if the round trip took 10 hours? 
:
Let d = one way distance to Calif
:
Write a time equation, Time = dist/speed
To time + return time = 10 hrs
{{{d/55}}} + {{{d/65}}} = 10
multiply equation by (55*65), solve for d
