A pipe press can produce 360 feet of pipe in 240 minutes. What is the production rate in yards per hour?

The press produces 360 feet in 240 minutes, so in 60 minutes it produces 360 × (60 ÷ 240) = 90 feet. Since 3 feet equal 1 yard, 90 feet is 30 yards. The production rate is 30 yards per hour, which is choice B.
