tree planting problem
1 tree planting problem on non closed line can be divided into the following three cases:
1 if trees are to be planted at both ends of non closed line, then:
number of trees = number of sections + 1 = total length ÷ Plant spacing - 1
total length = plant spacing ×( Plant number - 1)
plant spacing = total length ÷( (2) if trees are to be planted at one end of the non closed line and not at the other end, then:
number of trees = number of sections = total length ÷ Plant spacing
total length = plant spacing × Number of plants
spacing = total length ÷ (3) if trees are not planted at both ends of the non closed line, then:
number of trees = number of sections-1 = total length ÷ Plant spacing - 1
total length = plant spacing ×( Plant number + 1)
plant spacing = total length ÷( Number of trees + 1)
2 the quantitative relationship of tree planting problems on closed lines is as follows
number of trees = number of sections = total length ÷ Plant spacing
total length = plant spacing × Number of plants
spacing = total length ÷ Number of plants
profit and loss
(profit + loss) ÷ The difference between the two distributions = the number of shares participating in the distribution
(big profit small profit) ÷ The difference between the two distributions = the number of shares participating in the distribution
(big loss small loss) ÷ The difference between the two distributions = the number of shares participating in the distribution
encounter problem
encounter distance = speed and distance × Encounter time
encounter time = encounter distance ÷ Speed and
speed and = distance ÷ Encounter time
pursuit problem
pursuit distance = speed difference × Pursuit time
pursuit time = pursuit distance ÷ Speed difference
speed difference = pursuit distance ÷ Catch up time
flow problem
downstream velocity = hydrostatic velocity + flow velocity
countercurrent velocity = hydrostatic velocity - flow velocity
hydrostatic velocity = (downstream velocity + countercurrent velocity) ÷ 2
flow velocity = (downstream velocity countercurrent velocity) ÷ 2
concentration problem
weight of solute + weight of solvent = weight of solution
weight of solute ÷ Weight of solution × 100% = concentration
weight of solution × Concentration = weight of solute
weight of solute ÷ Concentration = weight of solution
profit and discount
profit = selling price cost
profit margin = profit ÷ cost × 100% = (sold price) ÷ Cost - 1) × 100%
up and down amount = principal × Up and down percentage
discount = actual selling price ÷ Original price × 100% (discount < 1)
interest = principal × interest rate × Time
after tax interest = principal × interest rate × time ×( 1-20%)

4. About an hour or so
you have to make sure where you are going from Ningbo. For example, from Ningbo north bus station to Dinghai long distance passenger transport center in Zhoushan, the whole journey is about an hour. If you go to Ningbo from Fenghua or Yuyao in Ningbo, it will take more than two hours, or maybe longer
Ningbo is big, so is Zhoushan. For example, if you want to go to Shenjiamen in Zhoushan, it will take you another half an hour to get to the passenger transport center in Shenjiamen. If it is to Shengshan Town, then it is estimated that it will take one day, that is, 12 hours, to join the ticket is not so long
you have to have a specific place of departure and arrival, which can give you a more accurate time.

5. Ningbo passenger transport center takes bus 501 or 369 Ningbo south station, from Ningbo south bus station to Dinghai, Zhoushan. There are buses from 6 a.m. to 7 p.m. Now you don't need to take a boat to cross the sea bridge. It's only 1.5-2 hours from Ningbo south bus station to Dinghai, Zhoushan.
