Randy should begin his homework by 07:10 in order to sleep by 10:00
How to determine the time to start the homework?
The given parameters are:
- Social studies = 45 minutes
- Science = 40 minutes
- Math = 1 hour and 15 minutes
- Bed preparation = 10 minutes
If the above activities are done, the time spent would be:
Time = 45 minutes + 40 minutes + 1 hour and 15 minutes + 10 minutes
Add the time
Time = 2 hour and 50 minutes
He wants to go to bed by 10:00.
So, the time to begin his homework is:
Begin = 10:00 - 2 hour and 50 minutes
Evaluate the difference
Begin = 07:10
Hence, Randy should begin his homework by 07:10
