The document discusses converting rates between different units. It provides examples of converting a shuttle's rate of ascent from miles per minutes to miles per second. It also converts the shuttle's orbital speed from miles per hour to feet per second using known conversion rates.

1. Agenda Wed. Dec. 9 homework 13 p. 185 # 1 - 6, 11 - 13, 32 - 40 Correct homework Ch. 4-1 Ex. 1 & 6 Unit Rates, Conversions & proportions

5. Move the blocks to fill in the blanks with our new terms. A ____________ is a ratio that compares two units. A _____________ is a _____________ per one given unit. Rate Unit Rate Rate

6. Converting a rate to a unit rate The space shuttle Endeavor climbed 71 miles in about 8.5 minutes. Let's look at the shuttle's rate of ascent. Rate Unit Rate 8.5 8.5 1 = . . 71 miles 8.5 minutes 8.4 miles 1 minute 71 8.5 8.4 = . . ?

7. Change miles to ____________ Making TWO changes The shuttle orbits at 17,400 miles/hour. What is the rate in feet per second? Change hour to ____________ Feet Second

8. What known rate can you use to convert hour to second? 17,400 miles 1 hour X = 1 hour 3600 seconds 4.83 miles 1 second 1 hour 3600 seconds 60 seconds 1 minute X 60 minutes 1 hour = How did I get that rate?

9. What known rate can you use to convert miles to feet? 4.83 miles 1 second X = 5280 feet 1 mile 25,502 feet 1 second 17,400 miles 1 hour 25,502 feet 1 second = So, that means...
