Question

DJ has finished 10% of an art project that has taken him a total of 4 hours so far. If he continues to work at the same rate, how many hours will it take for him to complete the entire project?

Answer 1

40 hrs

Explanation:

-Given that 10% of the work is done in 4 hrs.

-Determine how many 10% portions make up 100%

`=(100\%)/(10\%)\\\\=10`

-Given that the work rate is remains unchanged for the entire work period.

#We multiply the number of hours per portion by the total number of portions:

`t=hrs* portions\\\\=4* 10\\\\=\ 40\ hrs`

Hence, it will take 40 hrs to finish the job.
