Q: If a willow oak leaf is 5.5 inches long, how many centimeters is it? (Use $1 \mathrm{in} = 2.54 \mathrm{cm}$)

$5.5 \mathrm{in} \times 2.54 \mathrm{cm/in} = 13.97 \mathrm{cm}$

Q: Which of the following is the correct scientific notation for 10000.1 L?

$1.00001 \times 10^4 \mathrm{L}$

Q: Which of the following is a correct conversion for 0.000004 L into scientific notation?

Q: An osprey is flying at 45 km/hr during its spring migration. What is its speed in m/s? (Use $1 \mathrm{km} = 1000 \mathrm{m}$ and $1 \mathrm{hr} = 3600 \mathrm{s}$)

$45 \mathrm{km/hr} \times \frac{1000 \mathrm{m}}{1 \mathrm{km}} \times \frac{1 \mathrm{hr}}{3600 \mathrm{s}} = 12.5 \mathrm{m/s}$
