A spaceship travels \(36,000\ km\) in one hour. Express its speed in \(km/s\).

To convert \(km/h\) into \(km/s\), the value .

The formula of speed is given as

\(Speed\ =\) \(\frac{1} {{Distance} \times {Time}}\)
\(Speed\ =\) \({Distance} \times {Time}\)
\(Speed\ =\) \(\frac{Time}{Distance}\)
\(Speed\ =\) \(\frac{Distance}{Time}\)

On substituting the known values in the formula, we get \(km/s\).
