Question

frank is building a model airplane. he wants to take no more than 25hours to assemble it, and he already spent 9 hours on the model if he works for 2 hours a day, how many more days can he devote to the project ?

Answer 1

25 hours - 9 hours = 16 hours left to work on the model plane

 

Frank works two hours a day for n days until he works 16 hours.

 

(2 hours per day) x (n days) = 16 hours

 

n days = 16/2 = 8 days
