### Ammorn's Rate Growing Post

Part 1

Define:

Ratio- Compares two quantities measured in the same units.
Rate- Compares two quantities measured in different units.

The difference between ratio and rate are, ratio is measured in same units and rate is measured in different units.

Page 60,

4. Determine the unit rate in each situation.

a)An orca swims 110 km in 2 hrs
55 km/h

b) A Canada goose flies 800 hm in 12.4 h.
64 km/h

c) Cathy plant 45 daffodils in 30 min.
90 daffodils / hr

11. Shannon buys 12 granola bars for \$9.96.

a) Determine the price per bar. Give your answer in dollars and cents.
\$9.96 divided by 12 granola bars = \$0.83/ bar

b) Explain whether your answer in part a) is a ratio or rate.
Part a) is a rate because it compares two different units.

Coin Math Question
If the jar adds up to \$100 and there are 1800 coins, what's the unit rate for every dollar ?
