Math CentralQuandaries & Queries


Question from amanda, a student:

Two tuna boats start from the same port at the same time, but they head in opposite directions. The faster boat travels 10 knots per hour faster than the slower boat. At the end of 8 hours, they were 272 nautical miles had each boat traveled by the end of the 8 hour period?

Hi Amanda,

Here is a start.

Suppose the slower boat travels at $s$ knots. At what speed is the distance between the boats increasing? At the speed the distance between them reaches 272 nautical miles in 8 hours.
