Sandra is counting the cars heading south on the highway through her town.

She observes that 1 car passes every 6 seconds.

Show Worked Solution

\(1\text{ car/}6\ \text{seconds}=10\text{ cars/}\text{minute}\)

\(\therefore\ \text{Cars in 2 hours}\)	\(=2\times 10\times 60\)
	\(=1200\)

\(\Rightarrow C\)
