Gordon8-16's Rate Growing Post

Hi I'm just going to cut to the chase.

Part 1

1. Ratio : Compares quantities of the same measurement
Rate : Compares quantit
ies of different measurements

A rate compares different measurements where as a ratio compares those of the same measurement.

2. Question 4 on page 60 asks us:
A) How many km per hour if you drive 110km in 2 hour's?
B) How many km per hour if you drive 800km in 12.5 hour's?
C) How daffodils did this girl plant per minute if she planted 45 in 30 minute's
Roughly 1.5 dafodile's/hr

3. Question 12 on page 61 asks us:
Which glacier melts faster if glacier A melted 1.5km in 75 years and glacier B metled 1320m in 70 years?
This one is a little more complicated first we convert the m into km by dividing by 1000 to get 1.32km now the answer is easy using a ratio table we get
Glacier A: 20m/year
Glacier B: 18.86m/year
Glacier A melted faster

4. Look at the coin question again from the ratio unit. Create a question that can be answered using rate. Answer that question.

How many coins per 5 cm of the jar?
Unfortunetly this cannot be answerd without the jar.

Part 2
