The velocity, , of an object in m/s is directly proportional to the time, , in seconds. This relationship can be expressed in the equation . Find the value of when m/s.
Given that varies directly as , write an equation for in terms of using as a non-zero constant.
If and when , determine the constant of proportionality.
