A plane travels a distance of 500 kilometers in 3600 seconds. What is the average speed of the plane?

A. 1.39 m/s
B. 69.4 m/s
C. 139 m/s
D. 0.694 m/s

Answer :

How long it takes an object to move a certain distance if we know its average speed and the total distance it covers. As previously, it makes no difference whether the speed is constant or not; all that matters is the average distance travelled. Thus, option C is correct.

What average speed of the plane?

The object's average speed is the total distance it travels in a predetermined amount of time. A scalar value represents the typical speed. It is characterized by the magnitude and lacks direction.

A body's average speed is its mean value over a given amount of time. Since a moving body's speed fluctuates over time and is not constant, an average speed formula is required.

Therefore, s = d/t s = 500×10^3/3600 s = 138.8 = 139 m/s. Distance travelled divided by time passed equals average speed.

Answer:

Option C, 139 m/s

Explanation:

s = d/t

s = 500*10^3/3600

s = 138.8 = 139 m/s
