Step 1
Explain one way the students could improve their method.
Answer
One way the students could improve their method is by increasing the distance between themselves, beyond the 50 meters shown in the diagram. A longer distance would ensure that the time taken for the sound to travel is more measurable, resulting in a more accurate calculation of the speed of sound.
Alternatively, they could use sound sensors or microphones instead of relying on human reaction times, which can introduce variability in their timing. This would allow for precise timing of the sound reaching Q.
