1) It takes 1435.75 hours for Mercury to complete a full rotation.

2) The weed can grow at 0.445 inches per hour.

Time calculation

1) Given that to make a full rotation, 59 days, 19 h, and 45 min goes by for Mercury, to determine how many hours does it take Mercury to complete a full rotation, the following calculation must be performed:

  • 59 x 24 + 19 + 0.75 = X
  • 1416 + 19.75 = X
  • 1435.75 = X

2) Given that a plant grows up to 0.89 ft per day, to determine how fast in inches per hour can this weed grow, the following calculation must be performed:

  • 0.89 / 24 = ft per hour
  • 0.037 = ft per hour
  • 1 ft = 12 inches
  • 0.037 x 12 = 0.445
