What is the Average Speed?
Distance: 10m
Time: 55
0 2m/s
15m/s
50m/s
O 20m/s

0.2m/s

Explanation:

speed =d/t

10/55= 0.181

approximately 0.2m/s

it is b.

Explanation: Average Speed = Total Distance  

                                                      Total Time

= 10m/5s

=2m/s

Hope this helps!!

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

gold is my favorite solid.
