Answer:

<em>The difference is 30 hours</em>

Step-by-step explanation:

<u>Proportions</u>

Safie can write a minimum of 5 questions per hour and a maximum of 11 questions per hour.

To write 275 she takes a maximum of 275/5=55 hours and a minimum of 275/11=25 hours.

The difference is 55 hours - 25 hours = 30 hours
