Question

An airplane flies 3080 km from Houston to New York in 4 hours what is the speed of the airplane

Answer 1

Answer:

The speed of the airplane is approximately 770 km/h (214 m/s).

Explanation:

Speed = $\frac{distance}{time}$

Distance = 3080 km

Time = 4 hours

speed = $\frac{3080}{4}$

           = 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 = $\frac{3080000}{14400}$

           = 213.8889

speed ≅ 214 m/s

The speed of the airplane is approximately 214 m/s.
