Question

A cloud is drifting across the sky at a constant velocity of 724metersperminute to the east. It is at an altitude of 9,200 meters. How far will the cloud move in 12.5minutes?

Answer 1

Answer:

The cloud moves 9050 meters to the east in 12.5 minutes.

Explanation:

Let suppose that mass of the cloud is negligible. meaning that effects of gravity are negligible and that altitude of the cloud remains constant. If the cloud drifts at constant velocity, travelled distance is defined by following formula:

$\Delta s = v\cdot \Delta t$ (1)

Where:

$v$ - Velocity, in meters per second.

$\Delta t$ - Time, in seconds.

If we know that $v = 724\,\frac{m}{min}$ and $\Delta t = 12.5\,min$, then the travelled distance after 12.5 minutes is:

$\Delta s = 9050\,m$

The cloud moves 9050 meters to the east in 12.5 minutes.
