The correct answer here is that if the skydiver is falling 176 feet persecond, he is falling 10560 feet per minute. This can be worked outquite easily, by considering that if there are 60 seconds in a minute,we then need to work out the proportion of 176 feet/1 sec = x/60 sec.You then need to multiply 60 by 176 to get 10560, which is your answer.
