An Olympic sprinter can run the $100.M$ dash in less than $9\mathrm{.}95s.$ What is his average speed in $m\frac{i}{h}r?$

A chemist needs $2\mathrm{.}00g$ of liquid compound as a reagent for a reaction. The density of the liquid is $0\mathrm{.}718\frac{g}{m}L.$ What volume of the liquid should she use? If the compound costs $$3\mathrm{.}51$ per milliliter, what is the cost to purchase $100mL$ of the reagent?

The U$.$S$.$ quarter has a mass of $5\mathrm{.}67g$ and is approximately $1\mathrm{.}5mm$ thick. How many quarters would you need to build a stack that reaches a height of $575$ feet $($the height of the Washington Monument$)?$ How much would that stack of quarters weigh in pounds $($lbs$.)?$ How much money $($in dollars and cents$)$ is that stack worth?

CHALLENGE: Most Teflon frying pans are manufactured with a Teflon coating that is $1\mathrm{.}00mm$ thick. The density of Teflo is $0\mathrm{.}805\frac{g}{c}m3.$ How many grams are needed to coat a pan with a surface area of $36\mathrm{.}0$ square inches? How many pounds of Teflo are needed to coat $150$ pans with the same area? $($Be careful here about converting the area!$)$
