conversations.value: Can you give me some step-by-step instructions for this math problem: Xavier plays football with his friends. During 15 minutes Xavier can score 2 goals on average. How many goals on average is Xavier able to score, when the match lasted for 2 hours?

conversations.value: Two hours means 2 * 60 = 120 minutes.
  So in 2 hours, there are with 120 / 15 = 8 groups of 15 minutes.
  So on average Xavier can score 8 * 2 = 16 goals.
