A plane can fly 3952 kilometers in 3 hours. If the plane flies in cloudy skies, it can fly 184 less kilometers than usual within the same time. What is the speed for the plane flies in cloudy skies?

Speed is a scalar quantity and it doesn't depend on direction

Speed is the total distance traveled divided by the total time taken

Speed = Total Distance / Total time taken

Given that,

A plane can traveled 3952 km in 3 hours normally.

So, it's normal speed is

Speed = total distance / total time

Speed = 3952 / 3

Speed = 1317.33 km/hr

Now, in cloudy skies it will traveled 184 km less than it's usually distance in the same time range.

Then, we want to find the speed in cloudy skies

Since we know that speed is total distance divide by total time,

We need to know the total distance in cloudy skies

Total distance = Normal distance travelled - delay due to cloudy skies

Total distance. = 3952 - 184

Total distance = 3768 km

Total time = 3 hours

Then,

Speed = total distance / total time

Speed = 3768 / 3

Speed = 1256 km/hr

The speed of the plane in cloudy skies is 1256 km/hr. The speed reduces because it traveled less distance for the same time.
