Question 117228: Solve.
Mark drove 250 miles to visit Sandra. Returning by a shorten route, he found that the trip was only 225 miles, but traffic slowed his speed by 5 miles. If the two trips took exactly the same time, what was his rate on the return trip? Answer by checkley71(8403) (Show Source):
You can put this solution on YOUR website! 250/R=225/(R-5) NOW CROSS MULTIPLY
R=50 MPH IS THE SPEED OF THE FIRST TRIP
50-5=45 MPH FOR THE RETURN TRIP.
