Question 916974: in the morning May drove to an appointment at 50 mph. her average speed on the return trip in the afternoon was 40 mph. the return trip took 1/2 hour longer . how far did she travel to the appointment Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! distance = x
Time to go there x/ 50
return time x/ 40
exrta time = 0.50 hour
x/ 40 - x/ 50 = 0.50
LCD = 7350 2000
multiply by LCD =
50 - 40 x 0.50 * 2000
10 x= 1000
/ 10
x= 100 miles
