Question 1055328: Randy drove from town to Dallas at average of 50 mph on the return trip he drove at the average speech of 55 mph the return trip took randy 1 hour less than the trip to dallas . how many total hour did he travel ? Answer by jorel555(1290) (Show Source):
You can put this solution on YOUR website! Let t stand for the time Randy was driving at the slower speed. Then:
55(t-1)=50t
55t-55=50t
5t=55
t=11
11 x 50=10 x 55=550 miles driven each way; 21 total hours driving. ☺☺☺☺
