Question

the time necessary for an object to travel along the z-axis (z) is equal to the quotient of the total units of position change on a straight line (p) and its constant velocity (u). (choose the formula that best expresses the statement.)
○ ( z = p div u )
○ ( z = p - u )
○ ( z = p \times u )
○ ( z = p + u )

Explanation:

The problem states that time \( z \) is the quotient (result of division) of position change \( p \) and velocity \( u \). So the formula should represent \( z \) as \( p \) divided by \( u \), which is \( z = p \div u \). The other options involve subtraction, multiplication, or addition, which don't match the "quotient" description.

Answer:

\( z = p \div u \)
