Answer:
The speed of the airplane is approximately 770 km/h (214 m/s).
Explanation:
Speed = ![\frac{distance}{time}](https://tex.z-dn.net/?f=%5Cfrac%7Bdistance%7D%7Btime%7D)
Distance = 3080 km
Time = 4 hours
speed = ![\frac{3080}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3080%7D%7B4%7D)
= 770
speed = 770 km/h
The speed of the airplane is 770 km/h.
OR
Distance = 3080 km
But,
1 000 m = 1 km
3080 km = 3080000 m
distance = 3080000 m
Time = 4 hours
60 seconds = 1 minute
60 minutes = 1 hour
Thus, 4 hours = 60 x 60 x 4
= 14400 seconds
Therefore,
speed = ![\frac{3080000}{14400}](https://tex.z-dn.net/?f=%5Cfrac%7B3080000%7D%7B14400%7D)
= 213.8889
speed ≅ 214 m/s
The speed of the airplane is approximately 214 m/s.
