If a vehicle travels 920 miles in 8 hours, what is its average speed?

To find the average speed of the vehicle, you need to use the formula for average speed, which is the total distance traveled divided by the total time taken.

In this case, the vehicle travels a total distance of 920 miles over a time period of 8 hours. To calculate the average speed, you can perform the following division:

Average Speed = Total Distance / Total Time

Average Speed = 920 miles / 8 hours = 115 miles per hour.

Thus, the average speed of the vehicle is 115 miles per hour. This confirms that the selected answer accurately reflects the result of the calculation based on the provided distance and time, making it the correct choice. Understanding this calculation method is important as it can be applied to similar problems regarding speed, distance, and time in various scenarios.
