Example:
A commuter train travels 44 kilometers in 31 minutes. What is its speed in kilometers per​ hour?
The speed is approximately 85.2 km/hr.


Problem:
A commuter train travels 55 kilometers in 41 minutes. What is its speed in kilometers per​ hour?
The speed is approximately BLANK km/hr or hr/km.

To calculate the speed of the commuter train in kilometers per hour (km/hr), you can use the formula:

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

First, convert the time from minutes to hours since speed is required in kilometers per hour.

\[
\text{Time in hours} = \frac{41 \text{ minutes}}{60} \approx 0.6833 \text{ hours}
\]

Now, use the distance traveled (55 kilometers) and the time in hours to find the speed:

\[
\text{Speed} = \frac{55 \text{ kilometers}}{0.6833 \text{ hours}} \approx 80.5 \text{ km/hr}
\]

Thus, the speed of the train is approximately **80.5 km/hr**.

1. What would the speed be if the train traveled 70 kilometers in 50 minutes?
2. How would you calculate the time taken if the speed and distance are known?
3. What is the speed in meters per second (m/s) for the same train journey?
4. How do you convert kilometers per hour to miles per hour?
5. What is the average speed of a vehicle that covers different distances at different speeds?

**Tip:** When converting minutes to hours, always divide by 60, as there are 60 minutes in an hour.
