SPEED If a car travels 400m in 20 seconds how fast is it going? D = S = ( ) ÷ ( ) = T = You arrive in my class 45 seconds after leaving math which is 90 meters away. How fast did you travel? It takes Serina 0.25 hours to drive to school. Her route is 16 km long. What is Serina’s average speed on her drive to school? TIME How much time will it take for a bug to travel 5 meters across the floor if it is traveling at 1 m/s? You need to get to class, 200 meters away, and you can only walk in the hallways at about 1.5 m/s. (if you run any faster, you’ll be caught for running). How much time will it take to get to your class? DISTANCE How far can you get away from your little brother with the squirt gun filled with paint if you can travel at 3 m/s and you have 15s before he sees you? How far can your little brother get if he can travel at 2.5 m/s and in 5 seconds you will discover that his squirt gun has run out of Calculations: A race car leaves the starting line and travels 36000 m in the first 600 seconds of the race. They are then forced to take a pit stop and don’t go anywhere for 250 seconds. After the pit stop, they finish the race, going 24500 m in 350 seconds. a) What is the car’s average speed during the first part of the race (before the pit stop)? b) What is the car’s average speed during the pit stop? c) What is the car’s average speed after the pit stop? d) What is the car’s average speed for the whole trip?
