It takes Ben 2 days to write 5 reports, and it takes Kate 3 days to write 5 reports. Ben's rate, in reports per day, is how much greater than Kate's rate?

A. [tex]\(\frac{5}{2}\)[/tex]
B. [tex]\(\frac{5}{3}\)[/tex]
C. [tex]\(\frac{5}{4}\)[/tex]
D. [tex]\(\frac{5}{6}\)[/tex]


Sagot :

Let's solve the problem step-by-step.

1. Determine the rates at which Ben and Kate write reports.

- Ben takes 2 days to write 5 reports, so his rate is:
[tex]\[ \text{Ben's rate} = \frac{5 \text{ reports}}{2 \text{ days}} = 2.5 \text{ reports per day} \][/tex]

- Kate takes 3 days to write 5 reports, so her rate is:
[tex]\[ \text{Kate's rate} = \frac{5 \text{ reports}}{3 \text{ days}} \approx 1.6666666666666667 \text{ reports per day} \][/tex]

2. Calculate the difference in their rates.
- Subtract Kate's rate from Ben's rate to find out how much greater Ben's rate is:
[tex]\[ \text{Difference in rates} = \text{Ben's rate} - \text{Kate's rate} = 2.5 - 1.6666666666666667 = 0.8333333333333333 \][/tex]

So, the difference in their rates, with Ben's rate being greater, is approximately 0.8333333333333333 reports per day.
