What is the Average Speed of a Train Traveling 18 km in 20 Minutes?

In summary, the average speed of a train is the total distance traveled divided by the total time taken to travel that distance. It is calculated by dividing the total distance traveled by the train by the total time taken to travel that distance. The average speed of a train is different from its instantaneous speed, as it takes into account any stops or changes in speed. Various factors can affect the average speed of a train, including distance, speed, stops, and delays. Knowing the average speed of a train is important for scheduling, planning, and understanding train efficiency.

The total distance traveled by trains is 18 km & the time spent is 20 minutes. Find the average speed of the train in kilometers per hour.

I' m stuck right in the beginning in converting 20 minutes to hours by dividing from 60 which I get this recurring decimal 0.33333

You don't need a decimal value...

\(\displaystyle \overline{v}=\frac{d}{t}=\frac{18\text{ km}}{\dfrac{1}{3}\text{ hr}}=54\text{ kph}\)

Thanks :D The times when you got to decide between fractions and decimals
 

FAQ: What is the Average Speed of a Train Traveling 18 km in 20 Minutes?

What is the definition of average speed of a train?

The average speed of a train is the total distance traveled divided by the total time taken to travel that distance. It is a measure of how fast the train is moving on average during a given journey.

How is the average speed of a train calculated?

The average speed of a train is calculated by dividing the total distance traveled by the train by the total time taken to travel that distance. This can also be represented by the formula: Average speed = total distance / total time.

How is the average speed of a train different from its instantaneous speed?

The average speed of a train is the overall speed of the train during a journey, taking into account any stops or changes in speed. Instantaneous speed, on the other hand, refers to the speed of the train at a specific moment in time.

What factors can affect the average speed of a train?

The average speed of a train can be affected by various factors, including the distance traveled, the speed of the train, the number of stops along the journey, and any delays or disruptions on the route.

Why is knowing the average speed of a train important?

Knowing the average speed of a train can provide valuable information for scheduling and planning train journeys, as well as understanding the efficiency of train operations. It can also help in calculating the estimated arrival time for passengers and freight.
