nadezda [96]

Answer:

$n\times \frac{1}{4}+(75-n)\times \frac{1}{3}$

Step-by-step explanation:

Given that:

4 papers are delivered by first person in one minute.

Rate of delivering one paper

Time taken to deliver one paper can be calculated by the formula:

$\dfrac{\text{Total Time taken}}{\text{Number of papers delivered}}$

Time taken to deliver one paper by first person = $\frac{1}{4}$

3 papers are delivered by second person in one minute.

Time taken to deliver one paper by second person = $\frac{1}{3}$

Total number of papers = 75

Number of papers delivered by first person = $n$

So, number of papers delivered by second person = ( $75-n$ )

Time taken to deliver $n$ newspapers = Number of newspapers delivered <em>multiplied by </em>Time taken to deliver one newspaper

Time taken by first person = $n\times \frac{1}{4}$

Time taken by second person = $(75-n)\times \frac{1}{3}$

So, Total time taken can be written as:

$n\times \frac{1}{4}+(75-n)\times \frac{1}{3}$
