Day 9

• What we will do today…

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?

3. A bug crawls 2 meters at a constant speed of 100 meters/second. How long will it take the bug to crawl?

4. A bird flies 100 meters/second in 50 seconds. How far will the birds travel?

5. Carlos lives 100 m away from his friend’s home. He travels an average speed of 500 meters/second to his friends home. How long will it take Carlos to get to his friends house?

Speed: Individual Group KWFL• Directions: On a poster paper, complete your

KWFL using the word problems your teacher gives you.

• Steps1.Half you poster paper into two sections. 2.Draw the KWFL chart on the top half. 3.Draw the KWFL chart on the bottom half.4.Fill in the KWFL for each word problem your

teacher gave you.

T-Chart: Speed vs. Velocity

• Draw the following T-chart.

Speed Velocity

Classify as velocity or speed

1. 2 m/s north2.3 km/hr3.8 cm/s4.300 m/s north5.8,000 km/ hr south6.4.5 miles/hours 7.3,000 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?

2. 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?
