A catchment is idealized as a 25 km ร 25 km square. It has five rain gauges, one at each corner and one at the center, as shown in the figure.
During a month, the precipitation at these gauges is measured as G1 = 300 mm, G2 = 285 mm, G3 = 272 mm, G4 = 290 mm, and G5 = 288 mm. The average precipitation (in mm, up to one decimal place) over the catchment during this month by using the Thiessen polygon method is _______.
Correct : 286.9 to 287.9
