Rephrased question: Did Richard travel more than 31680 feet in 30 mins?

a) In 30 mins he travels more than 30*60*16 = 28800. But not clear how much more if he traveled equal to or more than 31680 then question is answered.

b) In 30 mins he travels less than 30*60*18 = 32400. But not clear how much less if he traveled equal to or less than 31680 then question is answered.

Even after combining we know that range is
28800<R<32400

So there is no guarantee that he traveled 31680 feet. Thereby Answer E.
