L ETS R ECAP ! Rate: A comparison of two quantities measured in different units! Unit Rate: How many per ONE of the units!

T HE I NTIMIDATOR !!! Intimidator - NEW For Carowinds in 2010! - YouTube The Intimidator is the tallest, longest, and fastest roller coaster in the Southeastern US. Its top speed is 80 miles per hour. What does this mean????

Make sure you find your answer per hour and not per minute!! Stop 1: 15miles/hr Stop 2: 20 miles/hr Stop 3: 22.5 miles/hr Stop miles in 20 minutes Stop miles in 24 minutes Stop miles in 40 minutes

Part 1: 15 mph  Slowest!! Part 2: 20 mph Part 3: 22.5 mph  Fastest!!! What reasons could support the differences in speed? 22.5 mph > 20 mph > 15 mph

= 28 miles  How many miles Sascha travelled. 28/13 = 2.15 hrs or 2hrs and 9 minutes  How long it will take you with an average speed of 13mph

28 miles in 1.4 hrs 28/1.4  20 miles/hr

SUMMARY Write your answer at the bottom of your worksheet… In this problem, we found average miles per hour. What does average mean?
