How long does it take to travel 6 miles at a constant speed of 40 miles per hour?

To determine how long it takes to travel 6 miles at a constant speed of 40 miles per hour, you can use the formula for time, which is derived from the relationship between distance, speed, and time:

Time = Distance / Speed.

Plugging in the values from the question:

Time = 6 miles / 40 miles per hour.

This simplifies to:

Time = 0.15 hours.

Thus, it takes 0.15 hours to travel 6 miles at a speed of 40 miles per hour. This corresponds to 9 minutes, as there are 60 minutes in an hour and 0.15 hours times 60 minutes per hour equals 9 minutes. The answer accurately reflects the calculation based on the fundamental concepts of distance, speed, and time in physics.
