Answer:
The airplane travels 2400 kilometers in 3 hours at a speed of 800 kilometers per hour.
Another take:
But if you want the exact answer, it's 2399.976 km.
This way, you have both the rounded answer and the more precise calculation.
Answer:
2399.976 km
Step-by-step explanation:
v = 800 kmh^-1
= [800*1000/3600] ms^-1
=222.22 ms^-1
t = 3 h
= 3*3600 s
=10800 s
we know,
s=vt
=222.22*10800 m
=2399976 m
=2399.976 km
