### Karra's Rate growing Post

Ratio- A ratio is 2 or more quantitees that are compared in the same units.

Rate - A rate is 2 quantities that are compared in diffrent units.

One diffrence i think is that a ratop compares 2 things in the same unites and a rate is compared in 2 things in diffrent units.

Number 4.

a) A Orca swims 110 km in 2 hrs.

Answer: You can use a ratio table but i wont draw one. So for this question you have to divide 110 by 2 that =55. So our unit rate would be 55 km/hr.

b) A Canada goose flies 800 km in 12.5 hrs.

Answer: You divide 800 by 12.5 which =64 km/hr.

2. Trevor rode his mountain bike in 84 km in 3 h. Jillian rode 70 km in 2.5 hrs. Who is the faster cyclist? How do you know?

They are both the same.How I know is because I..

calculated 3 divided by 3 to get 1. If you do one thing to one side you have to do it to the other. So I divided 3 by 84 and got 28.

on the other ratio table I divided 2.5 by 2.5 to get 1. Since I did it to one side I have to do it to the other. So I divided 2.5 by 70 and got 28.

1. You could've put the ingredients in point form rather then a big paragraph so its not as complicated. Awesome job though!:)
