Question

Bella is riding her motorcycle directly south. In 2minutes, she covers 600meters of distance. What is her velocity?

300m/s

-0.2m/s

5 m/s

-5m/s

Answer 1

To calculate Bella's velocity, we can use the formula:

\[
\text{Velocity} = \frac{\text{Distance}}{\text{Time}}
\]

Here, the distance covered is 600 meters and the time taken is 2 minutes. However, we need to convert the time from minutes to seconds for consistency in units:

\[
2 \text{ minutes} = 2 \times 60 = 120 \text{ seconds}
\]

Now, we can calculate the velocity:

\[
\text{Velocity} = \frac{600 \text{ meters}}{120 \text{ seconds}} = 5 \text{ m/s}
\]

Since Bella is riding directly south, we can represent her velocity as negative if we take south as the negative direction. Therefore, her velocity would be:

\[
\text{Velocity} = -5 \text{ m/s}
\]

So, the correct answer is:

**-5 m/s**
