We will have the following:
1)
[tex]10\operatorname{km}\cdot\frac{0.621mi}{1\operatorname{km}}=6.21mi[/tex]
2)
[tex]\frac{14}{2}\frac{bales}{\text{week}}\cdot\frac{52\text{week}}{1\text{year}}=364\frac{bales}{\text{wek}}[/tex]
3)
[tex]\frac{85.4\text{yard}}{5\min}\cdot\frac{1\text{min}}{60s}\cdot\frac{16\text{inch}}{1\text{yard}}\cdot\frac{2.54\operatorname{cm}}{1\text{inch}}\cdot\frac{1m}{100\operatorname{cm}}\approx0.1156885333\ldots\frac{m}{s}[/tex]
4)
[tex]100lb\cdot\frac{1\operatorname{kg}}{2.2lb}\cdot\frac{1\text{quart}}{2.70\operatorname{kg}}=\frac{5000}{297}\text{quarts}\approx16.83501684\ldots quarts[/tex]
