After a skydiver's parachute opens, he or she descends at a rate of about 8 4/5 yard per second. in 7 seconds how many yards will a skydiver with an open parachute descend?

61 3/5 yards.

The sky diver is descending at a rate of 8 4/5 yards per second. So to determine how far they sky diver will descend in 7 seconds, just multiple 8 4/5 by 7.

8 4/5 * 7 = (7*8) + (7*4)/5 = 56 28/5

But 28/5 is an improper fraction. Normalize it and you get 5 3/5

Add the 5 to the 56 and you get

61 3/5
