On Tuesday, it rained for 4 hours at a rate of 2 inches per hour, and on Wednesday, it rained for 2 hours at a rate of twice that of the previous day.

conversations.value: On Monday, 7 hours of rain at a rate of 1 inch per hour is 7*1=7 inches of rain.
  On Tuesday, 4 hours of rain at a rate of 2 inches per hour is 4*2=8 inches of rain.
  Twice the rate of Tuesday is 2*2=4 inches per hour.
  Wednesday, 2 hours of rain at a rate of 4 inches per hour is 2*4=8 inches of rain.
  The combined total of the rainfall for these three days is 7+8+8=23 inches of rain.
