The document provides examples and explanations of unit rates, average speed calculations involving time and distance, and definitions and calculations for mean, median, and mode. It includes example word problems about driving distances and speeds, bike racing times, reading rates, kayaking distances and times, and averages involving numbers of students and canned food consumption. Formulas and steps are provided for calculating averages, distances, times, rates, and identifying the median and mode in data sets.

2. NOTES
Unit Rates = involve two units that form the rate
ex. 65 miles per hour (65 mph)
32 feet per second (32 ft/sec)
15 cents per ounce ($0.15/oz)

7. CLUMP CLUMP CLUMP
Cooper was traveling at an average rate of 58 miles per hour, about how long
would it take him to travel 20 miles?

SO, every minute = 1 mile
20 miles = ____ minutes?

8. YOUR TURN
Greyson kayaked along the Hawaiian shores at an average rate of 65 miles
per hour, about how long would it take him to go 10 miles before he
collapsed?

9. ZZZZZZZZZZZZZZZZZ
In Brittney’s favorite four 8th grade classrooms at Snowcrest have 28, 29,
31, and 32 students. What is the average number of students in an 8th
grade classroom?
28 + 29 + 31 + 32 = 120 120 ÷ ퟒ = ?
