3. 3

   Forward conversion

   $$\begin{array}{rl}1yd/s& =\frac{0.9144\cancel{m/s}}{0.44704\cancel{m/s}}\times 1\mathrm{mph}\\ & =\frac{0.9144}{0.44704}\mathrm{mph}\\ & =2.04545454545\mathrm{mph}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{mph}& =\frac{0.44704\cancel{m/s}}{0.9144\cancel{m/s}}\times 1yd/s\\ & =\frac{0.44704}{0.9144}yd/s\\ & =0.488888888889yd/s\end{array}$$
