Question

A space craft is at 452 m above the earth's surface. If it descends at the
rate of 5km per minute, what be its position after 9 hours?

Answer 1

Answer: (i) A space craft is at 4525 km above the earth's surface.

(ii) If it descends at the rate of 5 km per minute.

To find:

(i) Its position​ after 1 hour.

Solution:

We know that 1 hour = 60mins.

So, distance descended = (60*5) km

= 300km

New position after 1 hour = (4525-300) km

= 4225 km above earth's surface.

So, the new position is 4225km from earth's surface

The scientific value of biodiversity is relevant because our self-interest in biological resources supports economic and social benefits, such as wood, pharmaceuticals, cosmetics, and ecosystems .
