POW #5:A Cycling Problem
Orville and Wilbur owned a bicycle shop which also sold tricycles.One day,they decided to take an inventory of their stock.They each volunteered to count one item,which would have worked out just fine if one had counted bicycles and the other had counted tricycles.But,Orville and Wilbur were very independent thinkers.Orville counted the number of pedals in the shop and Wilbur counted the number of wheels.
Orville found that they had 144 pedals in the shop,and Wilbur found that they had 186 wheels.All pedals and wheels were actually parts of either bicycles or tricycles.They were just about to start over with their inventory when their friend,Kitty Hawkins,who was a good problem-solver,challenged them to figure out the number of bicycles and tricycles from the inventory they had already done.
Can you help the Wright brothers?
一个简单的计算题这个星期的POW相对简单……至少听起来是。你要做的就是说“Stanford”一百万次。没错，一百万次。 首先，做一些假设除了睡觉和吃饭，你
I can do ,but I cannot say english
2 and 3 144and 186
186-144=42
186 over 144 is 42
tricycles is 42
144/2-42=72-42=30
bicycles is 30
这是一道典型的“鸡兔同笼”问题.分析：每辆自行车有2个*,每辆三轮车有3个*.一、用算术先确定有多少辆车因为不管自行车还是三轮车每辆车的踏板都是2个,所以三轮车和自行车一共有：144÷2=72(辆)假设法：假设全...
就是一家自行车店也卖三轮车，找不到事了不去直接数自行车和三轮车各有多少，他要去数脚踏板和*的数量，有144个脚踏板和186个*，问自行车和三轮车各有多少？
设自行车有x辆，三轮车有y辆，则
2x+2y=144
2x+3y=186
x=30
y=42
即自行车有30辆，三轮车有42辆
