Over Lesson 2–5
Express the statement using an equation involving absolute value. Do not solve. The fastest and slowest recorded speeds of a speedometer varied 3 miles per hour from the actual speed of 25 miles per hour.
Over Lesson 2–5
Solve |p + 3| = 5. Then check your solution set.
Over Lesson 2–5
Solve | j – 2| = 4. Then check your solution set.
Over Lesson 2–5

Rate of Growth
BICYCLING The ratio of a gear on a bicycle is 8:5. This means that for every 8 turns of the pedals, the wheel turns 5 times. Suppose the bicycle wheel turns about 2435 times during a trip. How many times would you have to crank the pedals during the trip?
BICYCLING Trent goes on 30-mile bike ride every Saturday. He rides the distance in 4 hours. At this rate, how far can he ride in 6 hours?
Scale and Scale Models
MAPS In a road atlas, the scale for the map of Connecticut is 5 inches = 41 miles. What is the
distance in miles represented by 2 inches on the map?
