A student measures the time $t\,$ taken for a small glider to pass between two light gates on a linear air track.

They record three values for time $t$ :

0.53\text{ s}, \quad 0.48\text{ s}, \quad 0.56\text{ s}

Calculate the mean value of time $t\,$ to an appropriate number of significant figures.
