Let us assume the distance that Emma can jump = x
Then
The distance that Manny can jump = 4x/5
The distance that manny can jump is also given and that is = 40 inches
Then
4x/5 = 40
4x = 40 * 5
4x = 200
x = 50 inches
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the second option or option "B".
