A model hovercraft moves in a straight line through two light gates that are 1.20 m apart. A data logger records a travel time of 0.75 s between the hovercraft breaking the first beam and breaking the second beam.
Which calculation gives the average speed of the model hovercraft from the first light gate to the second light gate?
(1.20 m divided by 0.75 s) divided by 2
1.20 m divided by 0.75 s
(1.20 m + 0.75 s) divided by 2
0.75 s divided by 1.20 m
