, if Jeremy worked for 8 1/2 hours building model airplanes. If each airplane takes him 1 2/5 hours to make, how many models did he build?

Answer 1

To determine how many models Jeremy built, we need to divide the total time he worked by the time it takes him to make one model:

8 1/2 hours = 8 + 1/2 = 8.5 hours

1 2/5 hours = 1 + 2/5 = 1.4 hours

Number of models = Total time worked / Time taken to make one model

Number of models = 8.5 hours / 1.4 hours

Number of models = 6.07

Since Jeremy cannot make a fraction of a model, he would have built 6 models.
