Question

Are these rates equivalent?
25 minutes for 3$
1 hour for 6$

Answer 1

no

Explanation:

25 minutes for $3 ends up being $7.20 for 1 hour which is greater than 6.

Answer 2

no

Explanation:

We can use ratios to see if they are equivalent

25 minutes 60 minutes

---------------- = -------------------

3 dollars 6 dollars

Using cross products

25*6 = 3 * 60

150 = 180

This is not true so they are not equivalent
