Measuring Speed (Paperback)

Description

Did you know cheetahs can run 70 miles per hour? How do we know this? In this book, readers learn how to measure speeds like that of a cheetah using a simple formula and metric and imperial units. Diagrams, illustrations, and photographs further illuminate the knowledge presented and help readers fully grasp the concept. A concluding activity teaches readers to measure their own speed and puts their knowledge to the test.
