How can you find a unit rate when given a rate?

1 answer:

7 0

It depends on the problem really. One example is that you drive 10 miles in 2 hours. So you divide the distance over time to get 10/2 = 5. This means you drove 5 miles per hour (mph). The unit rate for this example is 5 mph.

Answer: y = 3/2x + 5
