Answer:
4752 ft/min.
Explanation:
The following data were obtained from the question:
Speed (in mph) = 54 mph
1 mile = 5280 feet
1 hour = 60 minutes
Speed ( in ft/min) =?
Next, we shall convert 54 mph to ft/h. This can be obtained as follow:
1 mph = 5280 ft/h
Therefore,
54 mph = 54 mph × 5280 ft/h / 1 mph
54 mph = 285120 ft/h
Finally, we shall convert 285120 ft/h to ft/min. This can be obtained as follow:
1 ft/h = 1/60 ft/min
Therefore,
285120 ft/h = 285120 ft/h × 1/60 ft/min / 1 ft/h
285120 ft/h = 4752 ft/min
From the calculations made above, 54 mph is equivalent to 4752 ft/min.
