5. Pg. 95 (set up as Cornell notes, titled Speed) Distance: the total length (km, m, cm) traveled; the total length of the path from start to end

6. Pg. 95 (set up as Cornell notes, titled Speed) Time: a measurable period (h, min, s)

7. Pg. 95 (set up as Cornell notes, titled Speed) Rate: a quantity compared to another quantity Examples (do not need to write): Crime rate (number of crimes PER year) Pay rate (dollars earned PER hour) Rate of travel AKA speed (distance PER time, like miles PER hour or centimeters PER second)

8. Pg. 95 (set up as Cornell notes, titled Speed) Speed: the rate something travels, calculated by distance divided by time Speed = distance time

9. Pg. 95 (set up as Cornell notes, titled Speed) MPH (Miles/hour): the common measurement for the speed of vehicles in the United States; expresses how many miles a car will travel in 1 hour Speed = distance time 65 MPH = 65 miles 1 hour
