Mme Q spent more time answering emails from students by 10 minutes

Step-by-step explanation:

Here we have

Time spent by Mme Q in answering mails on Friday given by

5/6 Hour = 50 minutes and

7/12 Hour = 35 minutes

Total time spent on Friday = 85 Minutes or

5/6 + 7/12 = 17/12 Hours

Time spent by Mme F in answering mails on Friday given by

1/2 Hour = 30 minutes and

3/4 Hour = 45 minutes

Total time spent on Friday by Mme F = 75 Minutes or

1/2 + 3/4 = 5/4 Hours

Therefore, Mme Q spent more time answering emails from students by 85 - 75 = 10 minutes.
