Question

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?

Answer 1

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
