Suppose the number of days it takes for the honeydew melons to be sold out is x days.
2(40x)=50x 360,
80x=50x 360,
30x=360,
x=12,
The number of white melons is: 12×40=480 (pieces),
The number of watermelons is: 480×2=960 (pieces),
Watermelons And Bailangua***: 480 960 = 1440 (pieces).
Answer: ***1440 watermelons and honeydew melons were shipped from the fruit shop.
So the answer is: 1440.
