Question

Choose the correct answer. Distance between 2 airports = 1,505 miles. Average speed of airplane = 420 mph. Flight time = hours.

Options:
a. 2.45 hours
b. 3.58 hours
c. 4.12 hours
d. 5.36 hours

Answer 1

The flight time for an airplane traveling 1,505 miles at an average speed of 420 mph is calculated to be approximately 3.58 hours. Hence, the correct answer is option b, which is 3.58 hours.

Step-by-step explanation:

To calculate the flight time of an airplane given the distance between two airports and the average speed of the airplane, we can use the formula for time, which is Distance divided by Speed. In this case, the distance between the two airports is 1,505 miles and the average speed of the airplane is 420 mph. Therefore, the flight time can be calculated as follows:

• Flight Time = Distance / Average Speed
  
• Flight Time = 1,505 miles / 420 mph
  
• Flight Time = 3.5833... hours

Rounding to two decimal places, the flight time is approximately 3.58 hours. Therefore, the correct answer is option b, 3.58 hours.
