In an experiment to measure the speed of sound, a student uses a stopwatch to find the time taken for a sound wave to travel from point A to point B. She repeats this experiment six times.
| Measurement | Time / s |
|---|---|
| First | 0.7 |
| Second | 0.9 |
| Third | 0.8 |
| Fourth | 0.6 |
| Fifth | 1.1 |
| Sixth | 0.7 |
Which value for the time should be used to calculate the speed of sound?
0.6 s0.6\text{ s}0.6 s
0.7 s0.7\text{ s}0.7 s
0.8 s0.8\text{ s}0.8 s
1.1 s1.1\text{ s}1.1 s
