conversations.value: This math problem has got me stumped: Chase and Rider can ride their bikes thrice a day for 5 days; but on two other days, they ride twice the times they do on usual days. How many times do they ride their bikes a week?
  Can you show me the way?

conversations.value: Each person rides his bike 3 x 5 = 15 times for 5 days.
  Together, they ride 15+15 = 30 times for five days.
  Each person rides his bike 3 x 2 = 6 times for every day of the other two days.
  This means each person rides 6*2 = 12 times on each day of the other two days.
  The total for the other two days is 12+12 = 24
  For the whole week the together ride 24+30 = 54 times
