What is the speed of a bus that travels a distance of 400.00 km in 420.0 mins?

To find the speed of the bus, we use the formula for speed:

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

Given:

- Distance = 400.00 km
- Time = 420.0 minutes

First, we need to convert the time from minutes to hours because speed is typically expressed in kilometers per hour (km/h).

\[
\text{Time in hours} = \frac{420.0 \, \text{mins}}{60 \, \text{mins/hour}} = 7.0 \, \text{hours}
\]

Now, plug the values into the speed formula:

\[
\text{Speed} = \frac{400.00 \, \text{km}}{7.0 \, \text{hours}} = 57.14 \, \text{km/h}
\]

So, the speed of the bus is **57.14 km/h**.

Would you like further details, or do you have any questions? Here are some related questions:

1. How would the speed change if the distance were increased?
2. What would the speed be if the bus took 6 hours instead?
3. How to convert speed into different units (e.g., m/s)?
4. What is the average speed concept, and how does it apply here?
5. How can you determine time if speed and distance are known?

**Tip:** Always convert units to the same system before performing calculations to ensure accuracy!
