Question

A copy machine can duplicate 2400 copies in one hour. How many copies can it make per minute?

Answer 1

Answer:

40

Explanation:

Copies made in 1 hour = 2400

1 hour = 60 minutes

Hence, copies made in 1 minute = 2400 ÷ 60 = 40

Answer 2

Answer:

The machine creates 400 copies per minute

Step-by-step explanation:

Let no. Of copy produced in one minute be x

2400 in one hour

1 hour = 60 minutes

By unitary method

60 minutes= 2400 copies

1 minute = x

Therefore 2400/6= x

So the value of x is 400.
