Starter: Word Problem • Directions: Using the word problem, identify what you know and what you will solve. What is the speed of a plane that traveled 3,000 miles from New York to California in 5.0 hours?
Practice Problems: Speed • Directions: Using the word problems, identify what you know, what you are solving for, the formula, and calculate the answer. 1. A frog jumped 2.5 kilometer in 1 hour, then jumped 5 kilometer in 2 hours, it rested for 1 hour, and then jumped 5 kilometer in 2 hours. What was the frog’s average speed?
2. Mark takes a 45 minute bike ride through the canyon a total of 4 kilometers. What is his speed?
A bug crawls 2 meters at a constant speed of 100 meters/second. How long will it take the bug to crawl?

T-Chart: Speed vs. Velocity • Draw the following T-chart. Speed Velocity
Classify as velocity or speed 1. 2 m/s north • 3 km/hr • 8 cm/s • 300 m/s north • 8,000 km/ hr south • 4.5 miles/hours • 3,000 meters/second
Practice Problem: Velocity Directions: Identify what you know, the formula, and calculate the velocity. 1. What is the average velocity of a car that traveled a distance of 50 km north in 2 hrs?
What is the velocity of jet that traveled 25,000 miles east from New York to Milan, Italy in 12 hours? 3. How long will it take a dump truck with a 5,000 ton load traveling 2,000 km east with a constant velocity of 10,000 km/hr?
