Answer:
12 trips
Explanation:
Eduardo cycles 12 kilometers per 3 trips
The unit rate would be 4 kilometers per 1 trip, because you divide each side by 3.
You can figure out that 28 divided by 7 equals 4. So, you can multiply the number of trips by 4
(3 x 4) equals 12
So, Eduardo takes 12 trips to cycle 28 kilometers
