While snowstorms in Middle Town, USA routinely leave up to 5 feet of snow on the ground, the first winter snowstorm deposits, on average, 18.7 inches of snow. According to the public works department, the snow removal rate is directly proportional to the number of inches of fallen snow. For the town’s fleet of snowplows to clear all the roads after a storm leaving 10 inches of fresh snow on the ground it takes 25 minutes. It takes one hour to clear the town’s roads of 24 inches of freshly fallen snow. If the rate of snow removal remains constant, how many minutes will it take to clear all the roads in the town after the first winter snowstorm, assuming it deposits 18.7 inches of snow? Express your answer to the nearest minute.
