Section 1: Describing Motion. Speed Speed is how far you travel over a period of time. Speed is expressed in the formula s=d/t (speed = distance/time).

 You can use weighted averages to solve uniform motion problems when the objects you are considering are moving at constant rates or speeds.

Motion Which way did it go?. What is Motion? Motion occurs when an object changes position over time.

Distance,Rate, and Time

Think! What information would you need to know to find out how long it takes to get to your friend’s house?

Suppose that you wish to travel by car to your favorite vacation spot at an average speed of 55 miles per hour. How many hours will it take you to travel 440 miles? How might you solve this problem?

The speed of the car represents the rate. The hours traveled represent the time. What relationship exists between the distance, rate, and time of the car? distance = rate x time

6

Formula Chart Distance, Rate, and Time distance= rate x time d=rt time = distance/rate t = d/r rate = distance/time r = d/t

Try These! A black bear runs 60 feet in 1 ½ seconds. What is its speed? A Barracuda can swim at a speed 60 meters per second. How far can it swim in 5 seconds? In 20 seconds?

Try These! 1.) d=________; r = 25 ft./sec; t = 18 sec 2.) d= 525 inches; r=_______in/sec; t= 30 sec 3.) d= 210 miles ; r = ______ mph ; t = 5h 4.) d =_________ ; r = 36mph ; t = 4h 5.) d= 360 miles; r = 60mph; t= ______h

More Practice Problems 1.) Suppose you traveled 990 miles to your favorite vacation spot. If you traveled at a rate of 55 mph, how many hours did you travel? 2.) You walk your dog 8 blocks in 16 minutes. How many blocks could you walk your dog in 2 hours? *Create your own problem using distance, rate, and time.
