How fast was I going if I drove 75 miles in 1.5 hours?

To determine the speed, you can use the formula for speed, which is distance divided by time. In this case, the distance traveled is 75 miles and the time taken is 1.5 hours.

Using the formula:

Speed = Distance / Time

You would calculate it as follows:

Speed = 75 miles / 1.5 hours = 50 miles per hour (mph)

This calculation shows that the average speed during the trip was indeed 50 mph. Therefore, this choice reflects the correct interpretation of the relationship between distance and time in this scenario. Understanding this formula is critical, as it applies to various situations in aviation and beyond, where speed calculations are essential for planning and safety.
