Write the equivalent rate.
8. 72+ft%2F4+sec+=+x+yd%2F+1+sec
72+ft%2F4+sec…first see how many ft%2F1sec, divide by 4

+%2872+ft%2F4+sec%29%2F4+=+%2872+ft%2F4%29%2F%284sec%2F4%29+=+%2818+ft%2F1sec%29+…… now
Since 1+ft+=+0.33333+yd then +18+ft=+6+yd,which means x=6
So we will have
72+ft%2F4+sec+=+6+yd%2F+1+sec
