Suppose the distance you travel to school is 5 mi. What is the total distance for 197 trips from home to school? Use mental math.

A scale is 1 cm: 20 m. Describe and correct the error in finding the actual distance that corresponds to 5 centimeters.

$$\begin{aligned} \frac { 1 \mathrm { cm } } { 20 \mathrm { m } } & = \frac { x \mathrm { m } } { 5 \mathrm { cm } } \\ x & = 0.25 \mathrm { m } \end{aligned}$$

If $m$ and $n$ are relatively prime positive integers, prove that

$$m^{\phi(n)}+n^{\phi(m)} \equiv 1(\bmod m n)$$

Stand flatfooted next to a wall and make a mark at the highest point you can reach. Then jump vertically and make another mark at the highest point. The distance between the marks is your vertical jumping distance. Use this distance to calculate your hang time.
