Question

What is the velocity of a car traveling on northbound I-5 that travels 200 meters in 30 seconds

Answer 1

Answer:

6.67 meters per second

Explanation:

Velocity is defined as the distance covered divided by the time it took to cover that distance. In your case the car traveled 200 meters in 30 seconds therefore its velocity is: $velocity = \frac{distance}{time} = \frac{200 m}{30 s} = 6.6666666 \frac{m}{s}$

This periodic fraction can be rounded to 6.67 m/s

Now, if they ask you what is the answer in meters per minute, you can give an integer value for your answer simply by using the equivalent of 30 seconds to minutes in the velocity formula:

$velocity = \frac{200 meters}{0.5 minutes} = 400 \frac{m}{min}$
