Question

A sixth grade teacher can grade 25 HW assignments in 20 minutes. Is he working at a faster rate or slower rate than grading 36 HW assignments in 30 minutes?

Answer 1

im not sure but he is grading assignments at a faster rate

Explanation:

25/20=1.25 so 1.25 mins per hw assignment

36/30=1.20 so 1.20 mins per hw assignment

it takes him 5 more seconds to grade 36 hw assignments so he's going at a faster rate

hope this helps :)
