Question

A train travels at the speed of 60 kilometre per hour from station to station be that and then came back with a speed 80 kilometre per hour from station to station to find the average speed and average velocity of the train​.

Answer 1

The average speed of the train is 40 miles per hour. The average velocity of the train is zero.

Step-by-step explanation:

1. To find the average speed of the train, we need to calculate the total distance traveled and the total time taken. The train travels 40 miles from station to station and then back, so the total distance is 80 miles. The average speed is calculated by dividing the total distance by the total time taken, which is (80 miles)/(1 hour + 1 hour) = 80 miles/2 hours = 40 miles per hour.
2. To find the average velocity, we need to consider the direction of motion. Average velocity takes into account both the magnitude (speed) and direction. Since the train returns to the initial station, its displacement is zero, meaning there is no net change in position. Therefore, the average velocity of the train is also zero.
