A bike moves a distance of 15
meters in a time of three seconds. What is the speed of the bike?

In this question, we are asked to
find the speed of a bike when we are given the distance it travels and the amount of
time it takes the bike to travel that distance. Recall that speed is the distance
an object travels divided by the time that the object travels for. So to find the bike’s speed, let’s
take the distance traveled, 15 meters, and divide by the time it takes to travel,
three seconds. That gives us 15 meters divided by
three seconds, which equals five meters per second. So the correct answer is five
meters per second.
