Question

An airplane takes off from Dallas, Texas, to fly to New York City traveling NE for 2,760 km. The same plane returns that day to Dallas. The airplane spent 2 hours on the trip to New York City, and the return trip took 2 hours. What is the airplane's speed for the round trip?

A. 1,104 km/h
B. 1,227 km/h
C. 1,300 km/h

Answer 1

The answer to your question is C

Answer 2

The right speed is:

• 1,380 km/h

Explanation:

You must remember that kilometers per hour refer to the number of kilometers traveled by a means of transport for each hour of travel, therefore, since it is known that the plane takes 2 hours to travel, you must divide the total kilometers in said number:

• Airplane speed = 2,760 Km/2 hours
• Airplane speed = 1380 Km/h

But since this option is not provided, the closest option is: C. 1,300 km/h.
