80m/s x 3.28 ft/m = 262.4 ft/s x 3600s/hr = 944649 ft/hr# -:# 5280 ft/mile = 178.91 miles/hr

Explanation:

First convert m/s to ft/s by multiplying 80 x 3.28. Then we can convert this answer to ft/hr by multiplying by 3600 (60s/m x 60 minutes/hr = 3600 s/hr). By dividing this number by the number of feet per mile we end up with the answer in miles per hour.
