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!
To calculate the total change in elevation after 5 seconds, we need to find the sum of the average change in elevation for each second. In this case, the parachutist has an average change of 110.5 feet per second for 5 seconds.
To find the total change in elevation, multiply the average change by the number of seconds:
Total change in elevation = average change in elevation * number of seconds
Total change in elevation = 110.5 feet/second * 5 seconds
To calculate this, simply multiply 110.5 by 5:
Total change in elevation = 552.5 feet
Therefore, the total change in elevation after 5 seconds is 552.5 feet.
You can arrive at this answer by multiplying the average rate of change by the duration of time for which it occurred.
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.
