The known facts in the given problem is that the object travels at the rate of 5 ft/sec.
Now we know that
Distance travelled in 5 second = 5 feet
Distance travelled in 1 second = (5/5) feet
= 1 feet
Distance travelled in 1 minute = (1 * 60) feet
= 60 feet
Distance travelled in 60 minutes = (60 * 60) feet
= 3600 feet
So the distance travelled by the object in 1 hour is 3600 feet.
