If an object travels at five feet per second, how many feet does it travel in one hour?

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.
