From 10:15 a.m. to 12:00 p.m. there are 1:45 hours. From 12:00 p.m. to 4:45 p.m. there are 4:45 hours therefore, each day Mr. Douglas works


1\colon45+4\colon45=6\colon30

hours.

Now, each week, Mr. Douglas works 4 days therefore, in one week, he works:


4*6\colon30

hours. Simplifying the above resut we get:


26\text{ hours.}

Finally, in four weeks Mr.Douglas works:


26*4\text{ hours=104 hours.}

Answer:


104\text{ hours.}
