Understanding Speed and Distance

What is the basic formula for calculating speed?

• Speed = Time x Distance

• Speed = Distance x Time

• Speed = Distance / Time

• Speed = Time / Distance

In the context of speed, what does 'per' mean?

• Divide

• Add

• Subtract

• Multiply

In the thunderstorm example, what is the speed of sound used?

• 400 meters per second

• 300 meters per second

• 350 meters per second

• 331 meters per second

What is the purpose of the 'mad T' method?

• To measure distance

• To calculate time

• To rearrange equations easily

• To memorize the speed formula

In the 'mad T' method, what does the horizontal line represent?

• Subtraction

• Addition

• Division

• Multiplication

How do you isolate distance in the formula V = D/T?

• Subtract V from both sides

• Multiply both sides by T

• Add T to both sides

• Divide both sides by V

What is the calculated distance to the storm if the time between lightning and thunder is 3 seconds?

• 1100 meters

• 900 meters

• 1000 meters

• 993 meters

Why is it important to perform a reality check after solving a problem?

• To ensure the units are correct

• To verify the solution makes sense

• All of the above

• To check for calculation errors

What is the rule of thumb for estimating distance based on the time between lightning and thunder?

• Every two seconds equals one kilometer

• Every three seconds equals one kilometer

• Every four seconds equals one kilometer

• Every second equals one kilometer

What units are used in the final calculation of the distance to the storm?

• Kilometers

• Meters

• Feet

• Miles
