Question

melissa has 14 reports to file, if each report takes an average of 1 hour and 15 mins, how long would it take to file 70% of them?

Answer 1

It would take 12 hours and 15 minutes

Answer 2

12 hours 15 min

Explanation:

Melissa has 14 reports to file.

She file 70% of report. She takes average of 1 hour and 15 minutes for each report.

First we find number of reported by Melissa.

Number of reported = 70% of 14

= 9.8

1 hour 15 min
`=(5)/(4)` hours

For 1 report of file
`=(5)/(4)` hours

For 9.8 reports of file
`=9.8* (5)/(4)\approx 12.25` hours

She will take 12.25 hours to report 70% of them.

12.25 hours = 12 hours 15 min

Hence, Melissa will take 12 hours 15 min to file 70% of report.
