Answer

To find the mean speed, we first add all the measured speeds together:

extTotalSpeed=1.31+1.27+1.16=3.74extm/s ext{Total Speed} = 1.31 + 1.27 + 1.16 = 3.74 ext{ m/s}

Next, we divide the total speed by the number of measurements (which is 3):

ext{Mean Speed} = rac{3.74}{3} = 1.25 ext{ m/s}

Thus, the mean speed is 1.25 m/s.
