For the previous question, how are they the same and how are they different?

Discuss the gist with your table and read the problem again to yourself.

Make sense of the problem

A band marches in the African American Day Parade in New York City. The band marches 800 meters every 15 minutes.

Discuss with your table how you would go about solving this problem.

What was the answer to the question? How do you know your answer is reasonable? Respond here with..My answer makes sense because...

Let's look at some strategies....

1000 meters = 1 kilometer

​Meters	​Kilometers
1,000 ​	1​
1​	.001​
800​	​.8

​You can use a table of equivalent ratios to convert between units of measure.

Minutes	Hours
60	1​
1​5	1/4

60 minutes = 1 hour

​The band marches 0.8 kilometers in hour. Multiply by 4 to find the number of kilometers the band marches in 1 hour.

4 x 0.8

You can multiply by a unit rate to convert between units of measure.

Write the rate for kilometers per meter.

1 kilometer = 1,000 meters

kilometer per meter

Find the number of meters the band marches
in 1 hour.

4 800 = 3,200

To convert 3,200 meters to kilometers, multiply by the unit rate.
