What is needed to figure out speed
Answers
Answer:
Speed tells us how fast something or someone is travelling. You can find the average speed of an object if you know the distance travelled and the time it took. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.

We can use formulas to model real-life situations.
For example, the formula for calculating speed is speed = distance ÷ time.
It is possible to calculate the speed, distance or time if you have the other two values.

WHAT YOU NEED: A whiteboard, pens, a board rubber and a calculator to check your answers.
A whiteboard with the formula for speed written on it
A whiteboard with the formula for speed written on itSTEP 1 - Write the formula Speed = Distance/Time on the board.
A whiteboard with the problem 150m divided by 25s
A whiteboard with the problem 150m divided by 25sSTEP 2 - Divide the distance travelled (150 metres) by the time it took to travel (25 seconds).
A whiteboard with the problem 150m divided by 25s
A whiteboard with the problem 150m divided by 25sSTEP 3 - Do the calculation 150 divided 25. You can use a calculator if you need to! The answer should be 6.
A whiteboard with the problem 150m divided by 25s
A whiteboard with the problem 150m divided by 25sSTEP 4 - Now add the units. Meters are divided by seconds, so the answer is 6 m/s (metres per second). Make sure to always put the units at the end of your answer!

To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
