If you are flying to a city 800 miles away, what will be the difference in flight times between flying into a 40-mph headwind and flying with a 40-mph tailwind if the plane's maximum speed with no wind is 160 mph?

Don't you read the answers that are posted for your questions??

To calculate the difference in flight times, we need to first determine the time it takes to fly 800 miles under the given conditions. Let's break it down step by step:

1. First, let's calculate the time it takes to fly with no wind. We know the plane's maximum speed with no wind is 160 mph. So, we can use the formula: time = distance / speed. In this case, the distance is 800 miles (as given in the question), and the speed is 160 mph. Therefore, the time taken to fly 800 miles with no wind is 800 / 160 = 5 hours.

2. Now, let's consider flying into a 40-mph headwind. In this case, we need to account for the reduced ground speed caused by the wind. The plane's airspeed will still be 160 mph, but the actual speed against the ground will be reduced. To find the ground speed, we subtract the headwind speed from the airspeed: ground speed = airspeed - headwind speed = 160 - 40 = 120 mph.

3. Using the ground speed of 120 mph, we can now calculate the time it takes to travel 800 miles with a 40-mph headwind. Again, we use the formula: time = distance / speed. The distance is still 800 miles, but the speed is now 120 mph (ground speed with the headwind). Therefore, the time taken to fly 800 miles with a 40-mph headwind is 800 / 120 = 6.67 hours (rounded to two decimal places).

4. Finally, let's consider flying with a 40-mph tailwind. In this case, the tailwind will increase the ground speed beyond the airspeed. To find the ground speed, we add the tailwind speed to the airspeed: ground speed = airspeed + tailwind speed = 160 + 40 = 200 mph.

5. Using the ground speed of 200 mph, we can now calculate the time it takes to travel 800 miles with a 40-mph tailwind, using the formula: time = distance / speed. The distance is still 800 miles, and the speed is now 200 mph (ground speed with the tailwind). Therefore, the time taken to fly 800 miles with a 40-mph tailwind is 800 / 200 = 4 hours.

In conclusion, the difference in flight times between flying into a 40-mph headwind and flying with a 40-mph tailwind is 6.67 hours - 4 hours = 2.67 hours (rounded to two decimal places).
