A parachutist jumped from and airplane at an elevation of 11,880 feet above ground. In the first 5 seconds, the parachutist had an average change in elevation of 110.5 feet each second. What was the total change in elevation after 5 seconds? PLEASE HELP! I HAVE TO TURN THIS IN WITHIN THE NEXT HOUR!

110.5 feet each second
times five seconds

The average is the sum of what fell each second divided by 5.
Multiplying by five gets the sum back.
