Question

Koto traveled 5,000 meters north from her house with an average velocity of 4.5 m/s.

What was the time of her trip? (There are 60 seconds in 1 minute.)

18.5 minutes
20.4 minutes
2 hours
3 hours

Answer 1

To find the time taken for Koto's trip, we can use the formula:

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

Given:
- Distance = 5000 meters
- Average Velocity = 4.5 m/s

Plugging in the values:

\[
\text{Time} = \frac{5000 \, \text{meters}}{4.5 \, \text{m/s}} \approx 1111.11 \, \text{seconds}
\]

Now, we need to convert seconds to minutes:

\[
\text{Time in minutes} = \frac{1111.11 \, \text{seconds}}{60 \, \text{seconds/minute}} \approx 18.52 \, \text{minutes}
\]

Rounding the value gives us approximately **18.5 minutes**.

Thus, the answer is **18.5 minutes**.
