If a vehicle travels 585 miles in 5 hours, what is its average speed?

• A. 117.6
• B. 118.5
• C. 115.2
• D. 117.0

Answer: (D)

To determine the average speed of a vehicle, you can use the formula for average speed, which is the total distance traveled divided by the total time taken. In this case, the vehicle has traveled 585 miles in 5 hours. Using the formula: Average speed = Total distance / Total time Substituting the given values: Average speed = 585 miles / 5 hours = 117 miles per hour. The closest value to 117 miles per hour in the choices is 117.0, making it the correct answer. This average speed calculation effectively demonstrates how to find speed by simply dividing distance by time, reinforcing the principle that average speed remains consistent over the total distance and time, provided the motion does not involve any stops or changes in speed.

To determine the average speed of a vehicle, you can use the formula for average speed, which is the total distance traveled divided by the total time taken. In this case, the vehicle has traveled 585 miles in 5 hours.

Using the formula:

Average speed = Total distance / Total time

Substituting the given values:

Average speed = 585 miles / 5 hours = 117 miles per hour.
