Bill, Bob, Frank and Jim, who are all taxi drivers, work a busy street that runs east-west. The street has no traffic lights.
Oddly enough, an equal number of pedestrians walk in each direction at 4 kph.
The 4 taxi drivers were discussing the best way to pick up a fare. Bill said he was going to sit beside a curb and wait for a fare to come along. Bob said he was going to cruise west at 4 kph; and therefore would have twice the chance of picking up a fare as Bill. Frank said he was going to cruise east at 8 kph and that his chances would then be twice as good as either Bill's or Bob's. Jim then claimed that they were all wrong. He was going to drivef west at 12 kph and his chanced of picking up a fare were twice as good as Frank's.
Of the claims made, which were correct, and which were wrong?
__________
Bill made no claims.
Bob's claim was wrong.
Frank's claim was correct.
Jim's claim was wrong.
See Deity's post below for full explanation.
Bill would be the only one to pick up a fare because he is stopped and the rest are driving. (Unless you assume they stop to pick up the fare)
Heh, Bob is driving at the same speed as the people are walking, assuming that one person is walking in that direction at that time, Bob will be pulled for kerb crawling :D
It's lonely being the leader? or it's lonely at the top?Quote:

Ummm, 12?
Can we assume that all the answers to the taxi question are wrong, and so stupid you didn't even stoop down low enough to respond to them ? :confused:

Givens:
x = number of pedestrians walking east
y = number of pedestrians walking west
x = y
Rate of x = 4 km/hr
Rate of y = 4 km/hr
Breakdown:
Bill sits by the curb waiting for a fare. Over the course of any amount of time, Bill's chances of picking up a fare are equal to the total number of pedestrians walking by, therefore equal to x + y.
Bob drives west at 4 km/hr. Over the course of time, he will pass twice as many people walking east as Bill does. However, he will be following exactly with those walking west. So Bob's chances of picking up a fare are equal to 2x + 0 or if he follows one person exactly, 2x + 1, which still is not double of Bill's chances.
Frank drives east at 8 km/hr. Over the course of time, he will pass three times as many people walking west as Bill. However, he will pass the same number of people walking east as those that walk by Bill. In total Frank's chances come out to 3y + x which is double to Bill's x + y, given that x and y are equal.
Jim drives west at 12 km/hr. He will pass 4 times as many people walking east as Bill. He will also pass 2 times as many people walking west. In total his chances of picking up a fare are 4x + 2y. This is not double to Frank's 3y + x.
After cleanup and substitution here's what we have:
Bill = 2x
Bob = 2x
Frank = 4x
Jim = 6x
It's punctuation, not a value, a?Quote:
