$1m=100cm\to1cm=0.01m\\1h=60min\to1min=\frac{1}{60}h\\========================\\\\4.6\times10^8\ cm/min=4.6\times10^8\times\frac{0.01m}{\frac{1}{60}h}=4.6\times10^8\times0.6\ m/h\\\\=\boxed{2.76\times10^8\ m/h}\\\\Answer:\fbox{A.}$

Since it's 0.6 kg for 5 gallons, we'd want to find the unit rate aka the amount of kg's per gallon. To find that, we have to see how many times 5 goes into 0.6, which is 0.6/5=0.12 for 1 gallon. Multiply that by 7 to get 0.84 for 7 gallons!

own Everything's Coming Up Roses flower shop. Your employee makes 4 deliveries per hour. The distance between the shop and the f

erma4kov [3.2K]

The journey is broken down into five segment

Shop - first delivery = $12 \frac{1}{3}$ miles
First delivery - second delivery = $8 \frac{3}{4}$
Second delivery - third delivery = $17 \frac{2}{8}$
Third delivery - fourth delivery = $23 \frac{2}{3}$
Fourth delivery - shop = $10 \frac{5}{10}$

The average distance for each segment are:
$[12 \frac{1}{3}+8 \frac{3}{4}+17 \frac{2}{8}+23 \frac{2}{3}+10 \frac{5}{10} ]$ ÷ $5$

$\frac{145}{2}$ ÷5 = $\frac{29}{2}=14 \frac{1}{2}$
