Time, Distance and Speed worksheet - Free Printable

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

$$
\text{Speed} = \frac{\text{Distance}}{\text{Time}}
$$

We'll use the triangle method shown in the image:
- Distance is at the top.
- Speed and Time are at the bottom.
- To find speed: Distance ÷ Time
- To find distance: Speed × Time
- To find time: Distance ÷ Speed

Problem 1:

John travels 300 km in 3 hours. What was his average speed in km/h?

- Distance = 300 km
- Time = 3 hours
- Speed = ?

$$
\text{Speed} = \frac{300}{3} = 100 \text{ km/h}
$$

✔ Answer:
Speed = 100 km/h

Problem 2:

Erika runs 100 m in 12 s. What is her average speed in m/s? Round to the nearest m/s.

- Distance = 100 m
- Time = 12 s
- Speed = ?

$$
\text{Speed} = \frac{100}{12} \approx 8.333\ldots \text{ m/s}
$$

Rounded to the nearest whole number:
$$
\approx 8 \text{ m/s}
$$

✔ Answer:
Speed = 8 m/s (rounded)

Problem 3:

A soccer ball travels 10 m in 1.2 s. What is the average speed in m/s? Round to the nearest m/s.

- Distance = 10 m
- Time = 1.2 s
- Speed = ?

$$
\text{Speed} = \frac{10}{1.2} = 8.333\ldots \text{ m/s}
$$

Rounded to the nearest whole number:
$$
\approx 8 \text{ m/s}
$$

✔ Answer:
Speed = 8 m/s (rounded)

✔ Final Answers:

#### 1.
- Speed = ?
- Distance = 300 km
- Time = 3 h
- Speed = 300 ÷ 3 = 100 km/h

#### 2.
- Speed = ?
- Distance = 100 m
- Time = 12 s
- Speed = 100 ÷ 12 ≈ 8.33 → 8 m/s

#### 3.
- Speed = ?
- Distance = 10 m
- Time = 1.2 s
- Speed = 10 ÷ 1.2 ≈ 8.33 → 8 m/s

📌 Summary:

| Problem | Distance | Time | Speed |
|--------|----------|------|-------|
| 1 | 300 km | 3 h | 100 km/h |
| 2 | 100 m | 12 s | 8 m/s |
| 3 | 10 m | 1.2 s| 8 m/s |
