Annie spent 2.5 hours doing homework. She spent 1/3 of the time on her history project. She spent 3/5 of the remaining time solving math problems. After that, Annie spent all remaining time writing an essay. How much time did Annie spend writing the essay?

Step-by-step explanation:

2.5 hours = 150 min

1/3 of 150 is 50 min, which means she spent 50 min on her history project = 100 min leftover

3/5 of 100 min is 60 min (1 hour) = 40 min leftover

She spent 40 min writing her essay
