Question

A helicopter is flying at a height of 1500 m. There is a helipad which is just below the helicopter at a height of 600 m from the ground. Taking upward movement of the helicopter as positive and downward movement as negative. Find the distance of helipad from the helicopter?

Answer 1

Upward movement is taken as positive while downward movement is taken as negative. Hence, from the question we can conclude that helicopter is moving downward. So, the distance of helipad from the helicopter will be negative integers.

$=-1500m+600m$

$=-900m$.

The negative sign here only indicates the direction (downwards). The distance between helicopter and helipad is 900 m.
