Problema Solution
The copy machine in your office can produce 22,400 copies in 7 hours. How many copies can it produce in 21 hours?
Answer provided by our tutors
The rate of the copy machine per hour is:
v = 22,400/7 copies per hour
We need to find the number of copies made in t = 21 hours.
To find the number of copies produced in t hours we need to multiply rate (v) with time (t), that is:
v*t = (22,400/7)*21 = 22,400*3 = 67,200 copies
The copy machine will make 67,200 copies in 7 hours.
