Question 626461: it takes a runner 18 seconds to run a distance of 264 feet. What is the runners speed in mph?
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
18 seconds * (1 min/60 seconds)*(1 hr/60 min) = 0.005 hours
264 feet * (1 mile/5280 feet) = 0.05 miles
-------------------------------------------------------
d = rt
0.05 = r*0.005
0.05/0.005 = r
10 = r
r = 10
So the runner's speed is 10 miles per hour.
