Question

Lamar has a rope that is 6 meters long. He cuts away a piece that is 1.21 meters long. How long is the remaining piece of rope?

Answer 1

For this case we have that the initial measurement of the rope is:

$x_ {i} = 6 \ m$

If a piece measuring 1.21 meters long is cut we have that the final measurement of the rope will be:

$x_ {f} = x_ {1} -1.21\\x_ {f} = 6-1.21\\x_ {f} = 4.79$

Thus, the final measurement of the rope is $4.79 \ m$

Answer:

4.79 meters
