Question

Nguyen peeled 80 oranges in 8 hours. At that rate, how many oranges

would he peel in 30 minutes?

Answer 1

5

Explanation:

half of 80 is 40 and half of 8hrs is 4hrs

half of 40 is 20 and half of 4hrs is 2hrs

half of 20 is 10 and half of 2hrs is 1hr

half of 10 is 5 and half of 1hr is 30min

Basically he peels 10 oranges an hour because 80 divided by 8 is 10 and half of an hour so half of 10 is 5
