To calculate the number of minutes, we have to convert the hours to minutes or we can calculate the difference between the starting and ending times to a fixed hour.

In this case, we will use the second approach.

We will use 10:00 am as the fixed hour.

Then, if she started reading at 9:45 am, 15 minutes had passed until 10 am.

If she ended reading at 10:37 am, 37 minutes passed from 10 am.

Then, we can add the two segments:


T=15+37=52\min

Answer: she read 52 minutes.
