If a vehicle travels 294 miles in 7 hours, what is its average speed?

To find 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 scenario, the vehicle has traveled a total distance of 294 miles in a total time of 7 hours.

To calculate the average speed, you would perform the following calculation:

Average Speed = Total Distance / Total Time

Average Speed = 294 miles / 7 hours

When you divide 294 by 7, you find that the average speed is 42 miles per hour. This value aligns with the choice that states 42.0, making it the correct answer.

The other options provide speeds that do not match the result of this calculation, either being rounded differently or calculated with errors, which confirms that 42.0 is indeed the average speed based on the given distance and time.
