Math Problem Statement

Rodney and Dennis are gleaning​ (collecting) corn from a cornfield that is 1.3 miles long. Rodney starts on one end and is gleaning corn at a rate of 0.35 miles per hour. Dennis starts on the other end and is gleaning corn at a rate of 0.30 miles per hour. If they start at the same time and continue to work at the same​ rate, how long will it be before Rodney and Dennis​ meet? Simplify your​ answer.
