Answers 1

Answer:

Here is the answer!!!!

Explanation:

Let the time taken be t.

Distance travelled= 450 km(Given)

Time taken by bus= 13-t

Time taken by car= t

Distance traveled by the bus= 30( 13-t)

Distance traveled by the car= 42(t)

Then, 450= 30(13-t)+42(t)

         450= 390- 30t +42t

          12t = 60

           t= 5 hours

Distance travelled by the car= 42(t)

                                               = 42*5= 210 km

Hope it helps you dear!!!!

Explanation:

• Chemoautotrophs can incorporate their own organic molecules from the fixation of carbon dioxide. These life forms can deliver their own source of nourishment, or vitality. The vitality or energy required for this procedure originates from the oxidation of inorganic atoms,. For example, iron, sulfur or magnesium. Chemoautotrophs can flourish in exceptionally brutal situations, for example, remote ocean vents, because of their absence of reliance on outside wellsprings of carbon other than carbon dioxide.

• Chemoautotrophs incorporate nitrogen fixing microscopic organisms situated in the dirt, iron oxidizing microorganisms situated in the magma beds, and sulfur oxidizing microbes situated in remote ocean warm vents.
