Question

A plumber has two pipes. One pipe is 7 times as long as the other pipe. He cuts 2.2 meters from the longer pipe. The remaining length of this pipe is 3 times that of the shorter pipe. Find the length of the shorter pipe in meters.

Answer 1

7x2.2 is 14.4 then you will need to multiply 3x2.2 then add them up

Answer 2

Length of the shorter pipe is 0.55 meters.

Explanation:

Let the length of one longer pipe = x meters and the length of shorter pipe = y meters

Now we will form the equations to get the length of shorter pipe or value of y.

x = 7y -----(1)

x - 2.2 = 3y ----(2)

Now we put the value of x from equation 1 to 2.

7y - 2.2 = 3y

7y - 3y = 2.2

4y = 2.2

y = 2.2/4 = 0.55 meters

Therefore the length of the shorter pipe is 0.55 meters.
