Aspace shuttle travels at the rate of 3,094 miles per hour to reach its orbit at a height of 300 km from earth. if 1 kilometer equals 0.62 miles, which of these conclusions is correct about the space shuttle?
it reaches its orbit in about 4 minutes.
it reaches its orbit in about 30 minutes.
after 5 minutes, it is 60 kilometers away from its orbit.
after 10 minutes, it is 60 kilometers away from its orb

Option A, It reaches its orbit in about 4 minutes.

Explanation:

The speed with which the space shuttle moves miles per hour.

The distance to which this space shuttle has to move is kilometers

Given

KM miles

So KM miles

Lets explore each option one by one

Option D-

So, the distance covered by space shuttle in 10 minutes is equal to

hence , option D is incorrect

Option C -

the distance covered by space shuttle in 5 minutes is equal to

miles

hence , option C is incorrect

Option B-

Time taken by space shuttle to reach orbit at 186 miles distance

hence , option B is incorrect

Therefore option A is correct

a covalent bond, specfically triple bond

1)

i))the process of preparing food by green plants in the presence of sunlight is called photosynthesis.

ii) leaf is the site for photosynthesis.

iii) it takes place as,

6h2o+6co2=c6h12o6+602
