Thanks :D The times when you got to decide between fractions and decimalsMarkFL said:You don't need a decimal value...
\(\displaystyle \overline{v}=\frac{d}{t}=\frac{18\text{ km}}{\dfrac{1}{3}\text{ hr}}=54\text{ kph}\)
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.
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.
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.
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.
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.
