conversations.value: Amy biked 12 miles yesterday. If she biked 3 miles less than twice as far as yesterday, how many miles did she bike in total in the two days?

conversations.from: assistant
conversations.value: Twice the distance Amy biked yesterday is 12*2 = 24 miles
  If Amy biked 3 miles less than twice as far as yesterday, she biked 24-3 = 21 miles today.
  The total distance she biked in the two days is 21+12 = 33 miles
