If a bus traveled 20 miles north on a straight path, and then traveled 20 miles back to the starting point, what would the velocity of the bus be?

The velocity of the bus be is 0 miles/second

Explanation:

Given, a bus travelled a distance of 20 miles north and 20 miles back to the starting point

Hence, total distance = 20 + 20 = 40 miles

Velocity is calculated by the formula:

Velocity =  

Displacement =

Velocity =

Therefore, the velocity of the bus is 0 miles/second

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

the answer is either b or c
