Drive 113 km at 47 km/h and another 113 km at 66 km/h.
When distance is same then average velocity can be found by using below formula:
Here
Now by putting the values
So

For an object to float the weight of the object must be balanced by the buoyancy force.
However an object will sink if the magnitude of the buoyant force is equal to the weight of the amount of fluid that has the same volume as the object.
The combination of symbols that shows the ratio of elements
in a compound is called chemical formula. A chemical formula is one of the ways
in expressing information about the ratio and proportion of atoms that consists
a particular chemical compound. This is done by using a single line pf chemical
symbols of elements, numbers, and sometimes parentheses, comma, dashes,
brackets and sometimes the positive and negative sign. Chemical formula can
completely specify the simplest structure of molecules and chemical substances.
