Looking through the glass floor of the Spinnaker Tower. Looking at the outdoor tables of the café below. No one is there. They are 100 metres away so it would take 4.5 seconds to travel from here to there. This can be calculated from the formula s=ut+½at2, where s is the distance to be travelled (100 metres), u is the initial velocity (zero) and a is the rate of acceleration (in this case 9.81 metres per second per second due to the gravity of the Earth). No one would sit there all day after that.
