Answer 2

Calculating Average Speed of the Train

To find the average speed of the train, we can use the formula:

Average Speed = Total Distance / Total Time

First, let's calculate the total distance and total time traveled by the train.

1. Total Distance Traveled: - The train traveled 15.5 km in 3 hours and 15 minutes. - Additionally, it traveled 13.5 km in 2 hours.

Therefore, the total distance traveled by the train is 15.5 km + 13.5 km = 29 km.

2. Total Time Taken: - The train took 3 hours and 15 minutes to travel 15.5 km. - It took 2 hours to travel 13.5 km.

To calculate the total time taken, we need to convert 3 hours and 15 minutes to hours. 15 minutes is 0.25 hours, so the total time taken is 3.25 hours.

Now, we can use the formula to find the average speed of the train:

Average Speed = Total Distance / Total Time

Average Speed = 29 km / 5.25 hours

Average Speed = 5.5238 km/h

Therefore, the average speed of the train is 5.5238 km/h.
