- Speed is a measure of distance travelled by an object divided by time
- A meter stick is used to measure distance
- A stopwatch is used to measure time
- Hence, the speed of an object can be measured using a meter stick and a stopwatch

- The speed of an object can be measured using a meter stick and a stopwatch
- A bicycle is a kind of object
- Therefore, the speed of a bicycle can be measured using a meter stick and a stopwatch

So, the speed of a bicycle can be measured using a meter stick and a stopwatch
