Question

Rosie ran directly toward her home at a constant velocity for 78 seconds. In one-third of that time, she ran 52 meters. What was Rosie’s velocity?

Answer 1

Rosie's velocity is the distance she ran divided by the time it took her to run that distance. Therefore, her velocity is 52 meters / (78 seconds / 3) = 52 meters / 26 seconds = 2 meters/second. Answer: \boxed{2}.
