how many more minutes does it take to end the job

Question

 

A photocopying machine takes 6 minutes to copy a given amount of pages . After
2/3
of the job has
been completed, how many more minutes does it take to end the job

 

 

Answer 1

If x is the number we are looking for then we can write this as an equation

x=6-(2/3*6)

this means that the amount of time left to complete the job is equal to the total amount of time the job takes minus 2/3 of the total time.

x=6-4

x=2 minutes
