You run in a race at a rate of 4 miles per hour for 60 minutes and your friend runs in the race at a rate of 3.5 miles per hour for 60 minutes.
Your friend starts running 10 minutes before you, and you run for a half hour
Friend: 40/60 × 3.5 = 2 1/3 miles
You: 30/60 × 4 = 2 miles
You won't catch up in a half hour
4 mph: = 4×5280
_______ =352 ft/min; y = 352x
60
3.5 mph: = 3.5×5280
________ = 308 ft/min; y = 308(x+10)
