If a vehicle travels 846 miles in 6 hours, what is its average speed?

To determine the average speed of the vehicle, you need to divide the total distance traveled by the total time taken. In this case, the vehicle travels 846 miles over a period of 6 hours.

The formula for calculating average speed is:

[

\text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}}

]

Substituting the given values into the formula:

[

\text{Average Speed} = \frac{846 \text{ miles}}{6 \text{ hours}} = 141 \text{ miles per hour}

]

This calculation reveals that the vehicle’s average speed is 141 miles per hour. This result aligns perfectly with the value provided in option B.

Considering the context of the question, average speed is a straightforward calculation based on dividing distance by time. The answer reflects a direct and simple mathematical operation that confirms the performance of the vehicle over the specified duration.
