Question
Sophie ran a total of 120 meters directly toward school at a constant velocity.
She ran one-third of that distance in 4 seconds.
What was her velocity?
Solution
To solve this problem, we first need to find out how far Sophie ran in 4 seconds. Since she ran one-third of the total distance in 4 seconds, we divide 120 meters by 3.
120 meters / 3 = 40 meters
So, Sophie ran 40 meters in 4 seconds.
Velocity is defined as the rate of change of displacement with time. It is given by the formula:
Velocity = Displacement / Time
Substituting the given values into the formula, we get:
Velocity = 40 meters / 4 seconds = 10 meters/second
So, Sophie's velocity was 10 meters per second.
