Question 498003: on his way to visit Soren, Peter averaged 7 mi/h on his skateboard and 4 mi/h walking. If Soren lives 6 mi away and the whole trip took 1 hr, how many miles did Peter travel by skateboard? Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! This example is similar:
----------------------
You can jog at a speed of 8 miles per hour, and run at a speed of 12 miles per hour. If you traveled 6 miles in 40 minutes, find the amount of time you jogged as well as the amount of time you ran.
---------------------------
40 minutes = 2/3 hours
---------------
d = distance jogging
-------
d/8 + (6-d)/12 = 2/3 hours
times 48
6d + 4(6-d) = 32
2d + 24 = 32
2d = 8
d = 4 miles jogging
---------
2 miles running
---------
