Calculating speed

Front

What is speed?

Back

Speed is the distance traveled per unit of time.

Front

What is the formula to calculate speed?

Back

S = d/t (Speed = Distance ÷ Time)

Front

How do you calculate average speed?

Back

To calculate average speed, divide the total distance traveled by the total time taken.

Front

If a dog runs 50 km in 5 days, what is its speed?

Back

10 km/day (50 km ÷ 5 days = 10 km/day)

Front

If a cat runs 15 km in 3 days, what is its speed?

Back

5 km/day (15 km ÷ 3 days = 5 km/day)

Front

What is the difference in speed between the dog and the cat?

Back

5 km/day (10 km/day - 5 km/day = 5 km/day)

Front

A train travels 25 km in 5 hours. What is its speed?

Back

5 km/hr (25 km ÷ 5 hours = 5 km/hr)

Front

What is the average speed of Ben’s balloon car that takes 5 seconds to travel 15 meters?

Back

3 m/s (15 meters ÷ 5 seconds = 3 m/s)

Front

What do you do to find speed if you know distance and time?

Back

You divide the distance by the time.

Front

What is the unit of speed in the metric system?

Back

Meters per second (m/s) or kilometers per hour (km/hr).
