conversations.value: Ralph is a member of the cross-country relay team. There are four other members on the team who run 3 km to complete their part of the race. Ralph runs twice as much as any member on his team to complete his part of the race. How long is the race?
conversations.from: assistant
conversations.value: 4 team members each run 3 km, so 4 x 3 = 12 km.
  Ralph runs twice as much as any team member and since team members each run 3 km, Ralph runs 2 x 3 km = 6 km.
  The length of the race is 6 km run by Ralph + 12 km run by the rest of the team = 18 km.
