Problema Solution
A copy machine makes 28 copies per minute. How many copies does it make in 3 minutes and 45 seconds?
Answer provided by our tutors
the rate of the machine is v = 25 copies/min
the time is t = 3 min 45 sec = 3 45/60 min = 3.75 min
the number of copies = v*t
the number of copies = 25*3.75
the number of copies = 93.75 copies
