Question

A copper wire was 240 meters long . After 60 meters was cut off, it was double the length of a steel wire. How much longer was the copper wire than the steel wire at first?

Answer 1

240 - 60 = 180

180 = 2x; x being the length of the steel wire.

180/2 = 90

x = 90

240 - 90 = 150

answer:

150
