Carol spends 17 hours in a 2-week period practicing her culinary skills. How many hours does she practice in 5 weeks?

Hint: Since we have been given the total amount of hours carol practices in 2 weeks we will first calculate the amount of time practiced in one week. After this step it will be easier to calculate the amount of hours spent by Carol in total 5-weeks for practicing her culinary skills.

Complete step-by-step answer:
We have been given the total time carol practices in 2 weeks i.e. 17 hours. From this information we can find the total amount of time spent by Carol in one week.
All we have to do is divide 17 by 2.
Therefore, time spent by carol practicing culinary skills in one week will be $ = \dfrac{{17}}{2} = 8.5 $ hours
i.e. 8.5 hours respectively.
Now they have asked us to find the total time required to practice for a total 5 weeks. All we have to do Is multiply the time required for one week with 5
i.e. total practice done in 5weeks = practice done in one week $ \times 5 $
 $
   = 8.5 \times 5 \\
   = 42.5 \;
  $
= 42 hours and 30 minutes.
Hence the total time she practices in 5 weeks will be 42 hours and 30 minutes.
So, the correct answer is “42 hours and 30 minutes”.

Note: Generally this type of sum get easier if you succeed in calculating the time period which is multiple of one as done above. Many times reverse information is also given and we are asked to find the initial information, for which the idea of solving remains the same as done for the above sum.
