A particular project can be completed by six people working eight hours a day for twenty days. To speed up completion of the project, eight workers were put on the project to complete the project in twelve days. How many hours a day must the workers put each day, in order to complete the job on time?

10

Step-by-step explanation:

10 because you have to do the first problem first. 6 people × 8 hours = the total of 48 then times the days (20) and get the answer of 960. Then what you do is 960 and divide it by 12 and get 80 then divide that by 8 getting the answer of 10
