1. Find each quotient. Multiplying and Dividing Integers COURSE 2 LESSON 1-8 a. –20 4 b. –42 –7 –20 4 = –5 The signs of the factors determine the sign of the quotient. –42 –7 = 6 1-8

2. You are riding your bicycle at a speed of 12 ft/s. Four seconds later, you come to a complete stop. Find the acceleration of your bicycle by using the formula: Multiplying and Dividing Integers COURSE 2 LESSON 1-8 acceleration = final velocity – initial velocity time The bicycle’s acceleration is –3 ft/s per second. Simplify. The negative sign means the bicycle is slowing. = –12 4 = –3 Substitute 0 for final velocity, 12 for initial velocity, and 4 for time. 0 – 12 4 = 1-8
