Final answer:
The fire engine will take approximately 9 minutes to reach the fire.
Step-by-step explanation:
To calculate the time it will take for the fire engine to reach the fire, we can use the formula:
Time = Distance / Speed
In this case, the distance is 6 miles and the speed is 40 miles per hour. Plugging these values into the formula:
Time = 6 miles / 40 miles per hour
Dividing 6 by 40 gives us 0.15 hours or 9 minutes.
