An airplane flies 750 miles due west in 1 1/2 hours and 750 miles due south in 2 hours. What is the average speed of the airplane?

the answer is distance over time.

total distance is 1500 miles total time is 3.5 hours.
1500/3.5=428.57 mph.

1500/3.5 = x/1

3.5x = 1500
x = 428.57 mph

Mr. Anders and Mrs. Rich each drove home from a business meeting. Mr. Anders traveled east at 100 kilometers per hour and Mrs. Rich traveled west at 80 kilometers per hours. In How many hours were they 100 kilometers apart

To find the average speed of the airplane, you need to calculate the total distance covered and divide it by the total time taken.

Step 1: Calculate the total distance covered by the airplane.
The airplane flies 750 miles due west and then 750 miles due south.
Total distance = 750 miles + 750 miles = 1500 miles.

Step 2: Calculate the total time taken by the airplane.
The airplane takes 1 1/2 hours (or 1.5 hours) to fly 750 miles due west, and 2 hours to fly 750 miles due south.
Total time = 1.5 hours + 2 hours = 3.5 hours.

Step 3: Divide the total distance by the total time to find the average speed.
Average speed = Total distance / Total time = 1500 miles / 3.5 hours.

Now, let's calculate the average speed.

Average speed = 1500 miles / 3.5 hours ≈ 428.57 miles per hour.

Therefore, the average speed of the airplane is approximately 428.57 miles per hour.
