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.
