Respuesta :
A copy machine makes 126 copies in 5 minutes and 15 seconds.
What is unitary method?
- "It is a process of finding the value of a single unit.
- "Based on that value we can find the value of the required number"
For given question,
A copy machine makes 24 copies per minute.
We know, 1 minute = 60 seconds
This means, a copy machine makes 24 copies in 60 seconds
Using unitary method,
[tex]\frac{60}{24}= 2.5[/tex]
This means to make 1 copy the machine requires 2.5 seconds.
Let the machine makes 'm' copies in 5 minutes and 15 seconds.
5 minutes and 15 seconds
= (5 × 60) + 15
= 315 seconds
the machine makes 'm' copies in 5 minutes and 15 seconds.
We need to find the value of m.
[tex]\Rightarrow m=\frac{315}{2.5} \\\\\Rightarrow m=126[/tex]
Therefore, a copy machine makes 126 copies in 5 minutes and 15 seconds.
