To answer this question you have to determine how many feet are in a mile and multiply it by 70. There are 5280 feet in a mile, so 5280 x 70= 369600. So he can run 369600ft in an hour. (im pretty sure lol, i feel like i may have misunderstood this question, are there any answer choices?)
1 minute = 60 seconds
300 seconds / 60 seconds = 5 minutes
Equation Form:
w x 2 
19
Divide both sides by 2:
w 9.5
So, w must be equal to or greater than 9.5 for this equation to work.
