Velocity is defined as the distance traveled divided by the time taken to travel that distance. In this case, the goldfish swam 98 centimeters in 2.8 seconds. To calculate the velocity, you divide the distance (98 cm) by the time (2.8 s): 98 cm / 2.8 s = 35 cm/s. This means the goldfish was moving at a constant speed of 35 centimeters per second across the pond.
