Calculating Speed - Free Printable

Let's solve each of these speed calculation problems step by step, using the basic formula:

> Speed = Distance ÷ Time
> Rearranged:
> - Distance = Speed × Time
> - Time = Distance ÷ Speed

We’ll show full working for each.

1. A polar bear is strolling at a speed of 2 m/s. What distance does the polar bear travel in 120 seconds?

Given:
Speed = 2 m/s
Time = 120 s

Formula:
Distance = Speed × Time

Working:
Distance = 2 m/s × 120 s = 240 metres

✔ Answer: 240 m

2. A car travels at 20 m/s. How long will it take for the car to travel 1000m?

Given:
Speed = 20 m/s
Distance = 1000 m

Formula:
Time = Distance ÷ Speed

Working:
Time = 1000 m ÷ 20 m/s = 50 seconds

✔ Answer: 50 seconds

3. A pupil is walking hurriedly to class because he is late. The pupil moves at a speed of 2 m/s, and takes 180 seconds to get to class. How far did he travel?

Given:
Speed = 2 m/s
Time = 180 s

Formula:
Distance = Speed × Time

Working:
Distance = 2 m/s × 180 s = 360 metres

✔ Answer: 360 m

4. An Olympic sprinter runs at 9.5 m/s. How long does it take the runner to travel 200m?

Given:
Speed = 9.5 m/s
Distance = 200 m

Formula:
Time = Distance ÷ Speed

Working:
Time = 200 m ÷ 9.5 m/s = 21.05 seconds (approximately)

You can write this as:
200 ÷ 9.5 = 2000 ÷ 95 = 400 ÷ 19 ≈ 21.05 s

✔ Answer: Approximately 21.05 seconds

5. A cyclist takes 1200 seconds (20 minutes) to travel 8km. What is the cyclist’s speed?

Given:
Time = 1200 s
Distance = 8 km = 8000 m (convert km to metres)

Formula:
Speed = Distance ÷ Time

Working:
Speed = 8000 m ÷ 1200 s = 6.67 m/s (rounded to 2 decimal places)

Alternatively:
8000 ÷ 1200 = 80 ÷ 12 = 20 ÷ 3 ≈ 6.67 m/s

✔ Answer: 6.67 m/s

6. An aeroplane travels at 245 m/s. How far will it travel in 5 minutes?

(Hint: convert time to seconds)

Given:
Speed = 245 m/s
Time = 5 minutes = 5 × 60 = 300 seconds

Formula:
Distance = Speed × Time

Working:
Distance = 245 m/s × 300 s = 73,500 metres

Convert to km:
73,500 m = 73.5 km

✔ Answer: 73,500 m or 73.5 km

7. The Earth moves around the sun at 30 km/s. How long will it take to travel 60,000 km?

Given:
Speed = 30 km/s
Distance = 60,000 km

Formula:
Time = Distance ÷ Speed

Working:
Time = 60,000 km ÷ 30 km/s = 2000 seconds

✔ Answer: 2000 seconds

(You could also convert to minutes: 2000 ÷ 60 ≈ 33.33 minutes, but the question doesn’t ask for that.)

✔ Final Answers Summary:

1. 240 m
2. 50 seconds
3. 360 m
4. 21.05 seconds
5. 6.67 m/s
6. 73,500 m (or 73.5 km)
