Answer:
30meter per second
Explanation:
Given that
Distance = 3000 meters
Time = 100seconds
Speed = distance /time
Substituting the values
Speed = 3000/100
Speed = 30meter per second
The average speed needed to cover the travelling will be 30meter per second.

The rock cycle is a basic concept in geology that describes the time-consuming transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each of the types of rocks is altered or destroyed when it is forced out of its equilibrium conditions.
        
             
        
        
        
<u>Answer:- </u> <em>Option a  </em>radial symmetry 
<u>Explanation:- </u>
 Most of the organisms have can either of the two types of symmetry:-
1. <em>Bilateral symmetry</em>- A body is said to have a bilateral symmetry when it can be divided into 2 equal halves on either side of a <em>single</em>  plane.
For e.g if you cut the letter M from middle vertically then you have two equal halves.
2. <em>Radial symmetry</em> - A body is said to be radially symmetrical if  it can be divided into similar halves in <em>any</em> plane. This means that the organism has its body parts arranged around a central main axis.
The <em>cnidarians whether in polyp or medusa from exhibit radial symmetry because if you cut them in any plane you will get equal halves.</em>
