Jimmy's class has 4 jump ropes, and their average length is 112 meters. one jump rope is 34 meters, the second jump rope is 1 meter, and the third jump rope is 212 meters. what is the length of the fourth jump rope?

In this problem, the average is already given. In order to solve for the missing length of jump rope we have the following solution:

Let x = be the total length

X = 4 (112)

X = 448

Therefore,

34m + 1m + 212m = 247m

448m - 247m = 201 length of the fourth jump rope
