The graph shows the constant speed of a train.
What is the speed of the train?
A. 1200 km/h
B. 300 km/h
C. 75 km/h
D. 4 km/h

Answers

Answer:

75 km/h

Explanation:

Speed = Distance divided by Time.

The train went a distance of 300 km in 4 hours. Therefore, the speed of the train is: 300 divided by 4 = 75 km/h

The speed of the train is equal to 75 km/h. Therefore, option (C) is correct.

What is speed?

The speed of a body can be defined as the distance traveled by an object in a particular time interval. The average speed can be defined as a scalar parameter as it exhibits only the magnitude but not the direction of motion.

The speed of an object can be calculated from the ratio of the distance of the object to the time required to cover that distance.

The equation for the calculation of the speed can be written as follows:

Speed =  distance /time taken

From the graph, at t = 2 h, the distance covered by train = 150 km

At time t = 4 h,  the distance covered by train = 300 km

[tex]\displaystyle Speed = \frac{300-150}{4-2}[/tex]

Speed = 150/2

Speed of the train = 75 Km/h

Therefore, the speed of the train is 75 km/h.
