Question

Daniel, Isabella, and Mia began their

homework at the same time.
Daniel finished his homework in 60 minutes.
Isabella finished her homework in 50% of
Daniel's time. Mia finished her homework in
150% of Daniel's time.
How long did Mia and Isabella each work?

Answer 1

50% of 60 is 30.

100% of 60 is 60, plus 50% is 60+30, which gets you 90.
