Calculation of Time Spent on Household Chores

To calculate the total time spent by the homeowner on household chores, we need to add the time spent on cooking and the time spent on laundry.

The homeowner initially planned to spend 1 hour and 5/6 (or 1.8333) hours on cooking and 1 hour and 3/5 (or 1.6) hours on laundry. However, it took her 1 hour and 1/4 (or 1.25) hours longer than expected to complete all the work.

To find the total time spent, we can add the planned time for cooking and laundry and then add the additional time it took her.

Calculation:

Planned time for cooking: 1 hour and 5/6 hours = 1.8333 hours Planned time for laundry: 1 hour and 3/5 hours = 1.6 hours Additional time taken: 1 hour and 1/4 hours = 1.25 hours

Total time spent = Planned time + Additional time Total time spent = 1.8333 hours + 1.6 hours + 1.25 hours

Now, let's calculate the total time spent by the homeowner on all the work.

Total time spent = 1.8333 + 1.6 + 1.25 = 4.6833 hours

Therefore, the homeowner spent approximately 4.6833 hours on all the household chores.
