Final answer:
The average speed of a car that traveled 75 miles in 3 hours is calculated by dividing the distance by the time, resulting in an average speed of 25 miles per hour (mph).
Step-by-step explanation:
To find the speed of a car that has traveled 75 miles in 3 hours, you can use the formula for average speed, which is the total distance traveled divided by the total time taken. The formula looks like this:
Speed
= Distance / Time
In this case, the distance is 75 miles, and the time is 3 hours. Performing the calculation:
Average speed = 75 miles / 3 hours = 25 miles per hour (mph)
Therefore, the car's average speed is 25 mph.
