Abdul plans schedules for several biologists who are researching the manatee. One biologist must travel from Newport to Russell Key. Later the biologist has a meeting in Islamorada. Abdul must use the map below to find the distance from Russell Key to Islamorada to determine how much time the biologist can spend on Russell Key. [diagram of a right-angled triangle, three points labelled "Russell Key", "Newport" and "Islamorada", one side labelled "13.2 mi.", the other "15.5 mi."] What is the distance in miles (mi.) from Russell Key to Islamorada?
The whole manatee/biologists/Abdul story is irrelevant and distracting, relies on an incredibly unlikely coincidence (the right-angle), assumes that Abdul is bright enough to get a map out and measure distances but not bright enough to measure the distance he actually cares about, and confusingly sets the reader up to expect a question about time rather than distance.
My version: "[diagram]. How far is it from Russell Key to Islamorada?" or skip the place names entirely and "[diagram] What is the length of the third side of this triangle?"
(edited to remove a comment about Islamorada -- turns out that it is a real place. It also turns out that the map seems to be using real place names, but not real distances, which can only serve to confuse people who know the area.)
