At a speed of 130 miles per hour and an output of 8 gallons per minute, how many gallons are sprayed per mile?

To find out how many gallons are sprayed per mile at a speed of 130 miles per hour with an output of 8 gallons per minute, we need to take a few steps.

First, determine how long it takes to fly one mile at 130 miles per hour. Since speed is measured in miles per hour, we find the time taken to travel one mile:

1 mile / 130 miles per hour = 1/130 hours

Next, convert the duration from hours to minutes because the output is given in gallons per minute. There are 60 minutes in an hour, so:

(1/130 hours) * (60 minutes/hour) = 60/130 minutes = 0.4615 minutes (approximately)

Now, we multiply this time by the output rate in gallons per minute. The output is 8 gallons per minute, so:

0.4615 minutes * 8 gallons/minute = 3.692 gallons

Rounding this to one decimal place gives approximately 3.7 gallons.

Hence, at a speed of 130 miles per hour with an output of 8 gallons per minute, about 3.7 gallons are sprayed per mile. This calculation aligns with the correct answer, which is 3
