Question 108790
2. In the following equation, if {{{x}}} is measured in {{{meters}}} and {{{t}}} is measured in {{{seconds}}}, identify the units on the variable {{{v}}}.   

{{{x*m = v*t*s}}}

{{{v = (x*m)/(t*s)}}}

{{{v = (x/t)(m/s)}}}

3. In the following equation, determine the units on {{{t}}} if {{{S}}} is measured in {{{dollars}}} and {{{p}}} is measured in {{{dollars- per- year}}}.   

{{{S=p*t}}}

{{{t = S(dollars)/p(dollars/year)}}}

{{{t = (S/p)year}}}
