conversations.value: Tom weighs 150 kg.  He manages to hold 1.5 times his weight in each hand while wearing a weight vest weighing half his weight.  How much total weight was he moving with?
conversations.from: assistant
conversations.value: He was carrying 150*1.5=225 kg in each hand
  So he had 225*2=450 kg in his hands
  The weight vest weighed 150*.5=75 kg
  So he had a total of 450+75=525 kg he was moving
