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

AcademicPhysicsNCERTClass 7

As given, a spaceship travels 36,000 km in one hour.

So, the speed of the spaceship $=36,000\ km/h$

$=36000\times \frac{1}{60\times60}\ km/s$    [Because $1\ hour=60\times60=3600\ seconds$]

$=10\ km/s$

Therefore, in $km/s$, the speed of the spaceship is $10\ km/s$.
