Question

GAMING You advance 3 levels in 15 minutes. Your friend advances 5 levels in 20 minutes.
Are these rates proportional? Show your work and explain.

Answer 1

3 / 15 = 1 / 5
5 / 20 = 1 / 4

so no, they are not. we know this because when you turn them into proportions and simplify them, the two rates are not equal
