What is the formula for time using the Cheater Circle?

• t = s * d

• t = d / s

• t = d * s

• t = s / d

How long did it take Timothy to drive 5000 meters at a speed of 8 meters per second?

• 600 seconds

• 650 seconds

• 675 seconds

• 625 seconds

What is the formula for distance using the Cheater Circle?

• d = t * s

• d = s * t

• d = t / s

• d = s / t

In the example with Charlotte, what is her walking speed?

• 1.5 meters per second

• 2.2 meters per second

• 3.0 meters per second

• 2.5 meters per second

How far did Charlotte walk in 120 seconds at a speed of 2.2 meters per second?

• 250 meters

• 240 meters

• 264 meters

• 280 meters

What is the importance of canceling like terms in mathematical calculations?

• To avoid errors

• To make the calculation faster

• To change the units

• To simplify the equation

What unit is used for time in the example with Timothy?

• Minutes

• Hours

• Seconds

• Milliseconds

Which of the following is NOT a future application of the Cheater Circle mentioned in the video?
