CAST 11 - Do Now 3/6

When a whale comes to the surface, it exhales warm air through its spout. Scientists want to collect samples from whale spouts to learn more about the health of whales.

Scientists are considering two methods for collecting samples:

1. Drone: A silent remote-controlled drone robot that flies over a whale and collects a sample quickly. The cost is $5,000.

2. Boat: A gasoline-powered speedboat that is already owned by the scientists. It drives up to a whale and a passenger collects a sample quickly. The cost is $0.
