Average Speed Calculation of a Train

Calculating the Average Speed of a Train

The average speed of a train can be determined by dividing the total distance traveled by the total time taken to travel that distance. In this case, the train travels 58 km in two hours and 71 km in four hours. Let's break it down step by step:

Step 1: Calculate the speed of the train for the first scenario, where it travels 58 km in two hours.

Speed = Distance / Time

Speed = 58 km / 2 hours

Speed = 29 km/hr

Step 2: Calculate the speed of the train for the second scenario, where it travels 71 km in four hours.

Speed = 71 km / 4 hours

Speed = 17.75 km/hr

Step 3: Find the average speed by taking the mean of the two calculated speeds.

Average Speed = (29 km/hr + 17.75 km/hr) / 2

Average Speed = 46.75 km/hr / 2

Average Speed = 23.375 km/hr

Therefore, the average speed of the train is 23.375 km/hr.

Note: It is important to note that the average speed is calculated by finding the mean of the individual speeds. In this case, the train's average speed is 23.375 km/hr based on the given data. However, further verification may be needed to confirm the accuracy of this calculation.

A train travels 58 km in two hours and 71 km in four hours, what is its average speed?

Speed is given as distance divided by time. I think that first you should simplify the two rates 58/2=29 km/hr and 71/4=17.75 km/hr. After that find the mean or average which is (29 + 17.75) / 2 = 23.375 km/hr. Therefore, it is safe to say that the average speed of the train is 23.375 km/hr. I am not sure about this.
