conversations.value: Solve the math problem: Roberto and Valerie are jumping rope at recess. Roberto can skip 4,200 times an hour. Valerie can skip 80 times a minute. If they jump rope for fifteen minutes straight, how many skips will they total?
conversations.from: assistant
conversations.value: Roberto skips 70 times per minute because 4,200 / 60 = 70.
  Together they skip 150 times a minute.
  They will skip 2,250 times because 150 x 15 = 2,250
