Henry was given this cool toy for his birthday; he can use it to tell how fast someone is moving at that moment in time. The toy must calculate the person's

To calculate a person's speed using a toy, we need some information. The basic formula to calculate speed is:

Speed = Distance / Time

Here's how we can use the toy to measure speed:

Step 1: Set up the toy
Make sure the toy is ready to measure speed. It should have a display screen or readings that show the calculated speed.

Step 2: Determine the distance
To measure speed accurately, you need to determine the distance the person is traveling. This could be the length of a track, the distance between two points, or any other known measurement.

Step 3: Set a specific time frame
Decide on a fixed time frame during which you want to measure the person's speed. It could be a second, a minute, or any other interval.

Step 4: Start the timer
Once the person starts moving, start the timer simultaneously. Make sure the timer is accurate and synchronized with the toy.

Step 5: Measure the time taken
While the person is moving, keep track of the exact time taken to cover the specified distance. Stop the timer as soon as they finish.

Step 6: Calculate the speed
Now that you have the distance and the time, you can calculate the speed using the formula: Speed = Distance / Time.

Step 7: Interpret and display the speed
Using the information from the calculations, the toy should display the person's speed. It could be in miles per hour (mph), kilometers per hour (km/h), or any other suitable unit.

Remember, the toy itself should be designed to accurately measure time or distance for the formula to work correctly.
