How fast was a plane flying if it traveled 4000 kilometers in 3 hours?

Answer 1

So you are trying to solve for a velocity, which is equivalent to a change in distance over a change in time:

Givens:

Δx = 4000 km

Δt = 3 hours

Equation:

V = Δx / Δt

Solution:

V = 4000km / 3 hours = 1333.33 km/hr

And since aviation standard is in English units:

V = 1333.33 km/h * (1 nautical mile / 1.852 km) = 719.9 knots

Answer:

V = 719.9 knots
