Question 114191
Write the equivalent rate. 

8.  {{{72 ft/4 sec = x yd/ 1 sec}}}

{{{72 ft/4 sec}}}…first see how many {{{ft/1sec}}}, divide by {{{4}}}


{{{ (72 ft/4 sec)/4 = (72 ft/4)/(4sec/4) = (18 ft/1sec) }}}…… now 

Since {{{1 ft = 0.33333 yd}}} then {{{ 18 ft= 6 yd}}},which means {{{x=6}}}
So we will have

{{{72 ft/4 sec = 6 yd/ 1 sec}}}
