Why does condensation form on the outside of a drinking glass

When water vapor (from condensation) comes close to something cold (like the drinking glass), the molecules of both the vapor and glass slow down and will form liquid water drops on the outside of the drinking glass.

Given that,

Distance, d = 10700 km

Time taken by the airplane to complete the destination, t = 12 hours

We need to find the speed of the airplane. It is equal to the total distance covered divided by total time taken. So,

We know that,

1 km = 1000 m

1 h = 3600 s

So,

So, the speed of the airplane is 891.66 km/h or 247.68 m/s.
