Let’s solve each problem one by one, using the formulas:
-
Distance = Time × Speed
-
Time = Distance ÷ Speed
-
Speed = Distance ÷ Time
We’ll go step by step for each question.

1. Steve throws the football 45 meters in 3 seconds. What is the average speed?
Use:
Speed = Distance ÷ Time
= 45 meters ÷ 3 seconds
=
15 meters per second
✔ Final Answer for #1:
15 m/s

2. Ashley runs 18 meters in 3 seconds. What was her average speed?
Use:
Speed = Distance ÷ Time
= 18 meters ÷ 3 seconds
=
6 meters per second
✔ Final Answer for #2:
6 m/s
---
3. Bart ran 500 meters in 25 minutes. What was his speed?
Use:
Speed = Distance ÷ Time
= 500 meters ÷ 25 minutes
=
20 meters per minute
*(Note: The unit here is meters per minute since time was given in minutes.)*
✔ Final Answer for #3:
20 m/min

4. Justin races 720 meters in 60 seconds. What is his average speed?
Use:
Speed = Distance ÷ Time
= 720 meters ÷ 60 seconds
=
12 meters per second
✔ Final Answer for #4:
12 m/s

5. Mike rides at 20 meters/second for 500 seconds. How far did he ride?
Use:
Distance = Time × Speed
= 500 seconds × 20 meters/second
=
10,000 meters
✔ Final Answer for #5:
10,000 meters

6. Sarah backstrokes at 8 meters per second. How long to complete 200 meters?
Use:
Time = Distance ÷ Speed
= 200 meters ÷ 8 meters/second
=
25 seconds
✔ Final Answer for #6:
25 seconds

7. Lauren drove 10 kilometers in 5 minutes. How many km per minute over the 60 km/h limit?
First, find her actual speed in
km per minute:
She went 10 km in 5 minutes →
Speed = 10 km ÷ 5 min = 2 km/min
Now convert the speed limit (60 km/h) to
km per minute:
There are 60 minutes in an hour →
60 km/h = 60 km ÷ 60 min =
1 km/min
So she was going:
2 km/min – 1 km/min =
1 km/min over the limit
✔ Final Answer for #7:
1 km/min over the limit

8. Tarantula covered 20 centimeters in 5 seconds. What was its average speed?
Use:
Speed = Distance ÷ Time
= 20 cm ÷ 5 seconds
=
4 centimeters per second
✔ Final Answer for #8:
4 cm/s
---
Final Answer:
1. 15 m/s
2. 6 m/s
3. 20 m/min
4. 12 m/s
5. 10,000 meters
6. 25 seconds
7. 1 km/min over the limit
8. 4 cm/s
