conversations.value: Solve the math problem: A car in the fast lane is traveling at 60 miles/hour. A car in the slow lane is traveling at half that speed. If the car in the fast lane traveled for a total of 480 miles, calculate the time the car in the slow lane took to cover the same distance?

conversations.value: At half the speed, the car in the slow lane travels at a speed of 1/2*60 = 30 miles per hour.
  To travel 480 miles, the car in the slow lane traveling at 30 miles per hour will take 480/30 = 16 hours
