Question

When a certain kind of bacterium takes a step, it moves 3 × 10^-7 meters. When Joe takes a step, he moves 0.75 meters. How many times larger is Joe's step than the bacterium's step? In scientific Notation

Answer 1

2.5 × 10^6 times larger

Explanation:

Each step bacteria = 3 * (10^(-7)) meters = 0.0003 millimeters Joes step bacteria = 0.75 meters.= 750 millimeters We then divide = 750/0.0003 = 2500000 = 2.5 × 10^6
