Final answer:
The average speed of the Zephyr train from Denver to Chicago was 124.777 km/h and 34.66 m/s.
Step-by-step explanation:
The average speed of the Zephyr train can be calculated by dividing the total distance traveled by the time taken. The total distance is given as 1633.8 km and the time taken is 13 hours, 4 minutes, 58 seconds.
To convert the time to hours, we need to convert the minutes and seconds to hours. 1 hour is equal to 60 minutes and 1 minute is equal to 60 seconds. So, 4 minutes is equal to 4/60 hours and 58 seconds is equal to 58/3600 hours.
Adding these values gives us 13 hours + 4/60 hours + 58/3600 hours = 13.083 hours.
Now we can calculate the average speed by dividing the total distance by the time taken:
1633.8 km / 13.083 hours = 124.777 km/h.
To convert the average speed from km/h to m/s, we need to multiply it by the conversion factor of 1000/3600. This gives us 124.777 km/h * 1000/3600 = 34.66 m/s.
Therefore, the average speed of the Zephyr train is approximately 124.777 km/h and 34.66 m/s.
