Solution:

Since there are 5280ft in 1 mile, we can find how many feet are in 15 miles.

Converting miles into feet, we have \(5280*15=79,200 \)feet.

So, he travels 79,200 feet in 1 hour or 60 minutes.

Since they're asking us to find how many feet he can travel in 1 minute, we can easily do: \(\frac{79,200}{60}=\boxed{1,320} \)

feet.

Via dimensional analysis solution:

15 m/hr x 1/60 hr/min x 5280 ft/m = 1320 ft/min (as Tertre found)
