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

Answer:

40 hrs

Step-by-step explanation:

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

-Determine how many 10% portions make up 100%

$=\frac{100\%}{10\%}\\\\=10$

-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:

$t=hrs\times portions\\\\=4\times 10\\\\=\ 40\ hrs$

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