2. #1 What is the formula for calculating speed?
Speed = Distance or Distance ÷ Time
Time

3. #2 What is the formula for calculating average speed?
Average Speed = Total Distance
Total Time

5. #4 A cat traveled 81 meters in 9 seconds. What is its speed? = 9m/s
S = D T
= 81m
9sec

6. #5 A turtle traveled 600 meters in 3 hours. What is its speed? S = D T
= 200m/h

7. #6 A car travels 312 kilometers in 12 hours. What is its speed?
= 26 km/h
S = D T
= 312km
12h

8. #7 A girl runs a 10 kilometer race in 2 hours. What is her speed?
= 5km/h
S = D T
= 10km 2h

9. #8 AS = TD TT = 60km + 0km + 40km 2h + 1h + 2h = 100km 5h = 20km/h
On a trip in a car, you travel 60 kilometers for the first 2 hours, then stop for an hour, and the last 2 hours you travel 40 kilometers. What is the car’s average speed for the trip?
AS = TD TT
= 60km + 0km + 40km
2h + 1h + 2h
= 100km 5h
= 20km/h

10. #9
Which has a greater speed, a hawk that travels 600 meters in 60 seconds or a tiny warbler that travels 60 meters in 5 seconds?
HAWK
S = D T
= 600m
60sec
= 10m/s
Tiny Warbler
S = D T
= 60m
5sec
= 12m/s

11. #10 AS = TD TT = 100km 2h = 50km/h AS = TD TT = 100km 3h = 33.3km/h
Two drivers start at the same time to make a 100 kilometer trips. Driver 1 takes 2 hours to complete the trip. Driver 2 takes 3 hours, but stops for an hour at the halfway point. Which driver had a greater average speed for the whole trip?
AS = TD TT
= 100km 2h
= 50km/h
Driver 1
AS = TD TT
= 100km 3h
= 33.3km/h
Driver 2

12. #11
George flew from Austin to New York City, a distance of 560 km. The trip took 4 hours. What was the speed of the jet?
S = D T
= 560km 4h
= 140km/h

13. #12
A bamboo plant grows 15 centimeters in 4 hours. At what average speed does the plant grow?
AS = TD TT
= 15cm 4h
= 3.75cm/h
= 3.8cm/h

Label the X axis Time (seconds) and the Y axis for Distance (centimeters).
Number each line
The first 3 seconds the turtle travels 2 centimeters
The turtle then rests for 4 seconds
The last 3 seconds the turtle travels 3 centimeters
