In 1949 Dr Last Post, pseudonym of JJL van Zuylen, publishes his book The great puzzle of dr Last Post. It is a beautiful anthology of puzzles from which he published in December 1945 include the Green Amsterdam, The Netherlands Free People and Free.
It was still war, when one morning, at 12 o'clock, Higginbotham, the faithful butler redhead Sir Patrick plants vs zombies 2 Youtellme, the servant was called to purchase. plants vs zombies 2 Counsel to the hall Ie there were 12 soldiers at the door, a sergeant and 11 men, tired of a long march. They had to lay off exactly 20 miles told the sergeant, and they had to report as soon as possible and at the same time in the next Closeby village. Was sometimes to get some vehicle here
"We have scrapped plants vs zombies 2 Pord," said the butler to the sergeant. "There may be in addition plants vs zombies 2 to the driver and four passengers does not exceed 20 miles per hour. How fast can your troops march? "
"Then I will tell you what we do," said Higginbotham. "I'm going to ride with four of your men, the other eight go on foot. I put the four men off the road somewhere, drive back and pick four of the others as soon as I that eight pedestrians to come. I also put four on the road and drive back to pick. The last four All what you have to do is, that you walk to your destination, go to I pick you. The rest I do. "
Car goes on road with four soldiers remaining 8 foot soldiers 1.Na miles a car coming and group of 8 spleen Aires each other and take car next four soldiers along for meeting point applies: a / 4 = (20-a) / 20 > a = -6.67 km> elapsed time T1 = 6.67 / 4 = 1.67 hours; 4 militaiuren continue walking 2 miles after next b coming car and group of 4 militaiures each other and the last four military car, meeting point applies here steps: b / 4 = (13.33 + 13.33-b). plants vs zombies 2 > B = 4.44 km elapsed time T2 = 4.44 / 4 = 1.11 hours. 3.resterende time T3 transport last 4 soldiers to destination = (20 - 6.67 - 4.44) / 20 = 8.89/20 = 0.44 hours
The Ford is 5 times as fast as the current military. If the Ford some distance with its four soldiers aboard, plants vs zombies 2 the military sales and empty reverses back to the other ongoing military are met, is the turning point at a distance that is three times as large as what the current military has made.
It holds only four of the twelve soldiers in the Ford. That must be a lot riding plants vs zombies 2 three times. All soldiers have a lot (a) run twice and allowed one piece (3a) ride once. Total 5a = 20 km So a = 4 km. (And 3a = 12 km.) Twice 4 km. walk lasts two hours. plants vs zombies 2 Once 12 km. ride takes 12/20 hours = 36 minutes.
Suppose one group travels with exactly 60 minutes, so 20 km range. Meanwhile, groups 2 and 3 lay off 4 km, difference in distance 16 km. As of 20 km / h, driving back the car, walking groups 2 and 3 to 4 km / h through the accumulated speed is 24 km / h! That should be 16 km bridge, they do together in 40 minutes.
The car is 100 minutes when a group continue to drive and get to the next group back. So after 200 minutes plants vs zombies 2 the car back to the third group, and then drive it even in 60 minutes to the finish line.
Answer
(1) x + r = 20 (walk + drive total distance) (2) x = y + z (walking group 1 and group 3 = walk 2) (3) r/20 + (RY) / 20 = y / 4 (time first group to exit point + time car back to boarding point group2 = Maturity Group 2 at entry point). (4) r/20 + (RY) / 20 + r/20 + (rz) / 20 = x / 4 (total driving time from entry point group 3 is equal to the maturity group 3)
