- A meter stick is used to measure distance
- Speed is a measure of distance travelled by an object divided by time
- A stopwatch is used for measuring time
- Hence, speed can be determined by measuring the distance with a meter stick and dividing that by the measurement of time from the stopwatch

- Speed can be determined by measuring the distance with a meter stick and dividing that by the measurement of time from the stopwatch
- A calculator is used for dividing
- Hence, the speed of an object can be measured using a meter stick, stopwatch, and calculator

- The speed of an object can be measured using a meter stick, stopwatch, and calculator
- A toy car is a kind of object
- So, the speed of a car can be measured using a meter stick, stopwatch, and calculator

Therefore, the speed of a car can be measured using a meter stick, stopwatch, and calculator
