Question

A copy machine makes

36

copies per minute. How many copies does it make in
4

minutes and
15

seconds?

Answer 1

144 copies

Explanation:

Divided 36 by60

Answer 2

There are 60 seconds in a minute.
To find out how many copies in a second, divide 36 by 60.
That is 0.6
Then you would calculate to see how much in 15 seconds,
0.6 times 15
9 copies in 15 seconds

then multiply 36 * 4 to see how many in minutes
144 copies in 4 minutes

153 copies in 4 minutes and 15 seconds.

Hope this helps :)
