Question 749902: Randy rode out of town on the bus at an average speed of 24 miles per hour and walked back at an average speed of 3 mile sper hour. How far did he go if he was gone for six hours? (Having trouble setting it up) Found 2 solutions by timvanswearingen, MathTherapy:Answer by timvanswearingen(106) (Show Source):
You can put this solution on YOUR website! Use distance=rate*time. You can set up a couple equations for d and set them equal to find t. Then you'll plug back in to find d.
The time t spent on the bus will be subtracted from 6 (since the total time was 6 hours). This will give the time spent walking:
Now set the two equal and solve for t, then plug the t back into one of the previous equations to find the distance:

Let distance to out-of-town destination, be D
Then time it took him to get to out-of-town destination =
Also, time it took him to return home =
Since it took him a total of 6 hours to complete the journey, then:
D + 8D = 144 ------- Multiplying by LCD, 24
9D = 144
D, or distance traveled to out-of-town destination = , or miles
You can do the check!!
