Question

A cope machine makes 32 copies per minute. How many copies does it make in 4minutes and 15 seconds?

Answer 1

135

Explanation:

1. divide 32 by 60 to get how many copies per second

`32/60 = 0.533`

2. convert 4min and 15 sec to seconds

it is 255 seconds

3. Multiply copies per second by number of seconds

`0.533(255) = 135.91`

4. Round down to whole number because you can't copy part of a paper

Answer 2

136

Explanation:

4 times 32 = 128

32/4=8

128+8=136
