Chapter 2 Speed Worksheet | PDF - Free Printable

Let's solve each problem step by step using the speed formula:

Speed = Distance ÷ Time
Distance = Speed × Time
Time = Distance ÷ Speed

1. If Steve throws the football 45 meters in 3 seconds, what is the average speed of the football?

- Distance = 45 meters
- Time = 3 seconds

$$
\text{Speed} = \frac{\text{Distance}}{\text{Time}} = \frac{45}{3} = 15 \text{ m/s}
$$

✔ Answer: 15 meters per second

2. If it takes Ashley 3 seconds to run from the batters box to first base and it is 18 meters to first base, what was her average speed?

- Distance = 18 meters
- Time = 3 seconds

$$
\text{Speed} = \frac{18}{3} = 6 \text{ m/s}
$$

✔ Answer: 6 meters per second

3. Bart ran 500 meters in 25 seconds. What was his speed?

- Distance = 500 meters
- Time = 25 seconds

$$
\text{Speed} = \frac{500}{25} = 20 \text{ m/s}
$$

✔ Answer: 20 meters per second

4. If Justin races his Chevy S-10 down the highway for 720 meters in 60 seconds, what is his average speed?

- Distance = 720 meters
- Time = 60 seconds

$$
\text{Speed} = \frac{720}{60} = 12 \text{ m/s}
$$

✔ Answer: 12 meters per second

5. Mike rides his motorcycle at an average speed of 20 meters/second for 500 seconds, how far did he ride?

- Speed = 20 m/s
- Time = 500 seconds

$$
\text{Distance} = \text{Speed} \times \text{Time} = 20 \times 500 = 10,000 \text{ meters}
$$

✔ Answer: 10,000 meters (or 10 kilometers)

6. Sarah backstrokes at an average speed of 8 meters per second, how long will it take her to complete the race of 200 meters length?

- Distance = 200 meters
- Speed = 8 m/s

$$
\text{Time} = \frac{\text{Distance}}{\text{Speed}} = \frac{200}{8} = 25 \text{ seconds}
$$

✔ Answer: 25 seconds

7. Lauren’s SUV was detected exceeding the posted speed limit of 60 kilometers per hour, how many kilometers per minute would she have been traveling over the limit if she had covered a distance of 10 kilometers in 5 minutes?

First, calculate her actual speed:

- Distance = 10 km
- Time = 5 minutes

But we need speed in km/h, so convert time to hours:

$$
5 \text{ minutes} = \frac{5}{60} = \frac{1}{12} \text{ hours}
$$

$$
\text{Speed} = \frac{10}{1/12} = 10 \times 12 = 120 \text{ km/h}
$$

Now, subtract the speed limit:

$$
120 - 60 = 60 \text{ km/h over the limit}
$$

But the question asks: "how many kilometers per minute" over the limit?

So convert 60 km/h to km/min:

$$
60 \text{ km/h} = \frac{60}{60} = 1 \text{ km/min}
$$

✔ Answer: 1 kilometer per minute over the limit

8. Tina’s calculations of the tarantula found that the spider was able to cover 20 centimeters in 5 seconds, what was the average speed of the spider?

- Distance = 20 cm
- Time = 5 seconds

$$
\text{Speed} = \frac{20}{5} = 4 \text{ cm/s}
$$

✔ Answer: 4 centimeters per second

✔ Final Answers Summary:

1. 15 m/s
2. 6 m/s
3. 20 m/s
4. 12 m/s
5. 10,000 meters
6. 25 seconds
7. 1 km/min over the limit
8. 4 cm/s
