WorriSUM problems

Children in the U.K. will be asked to work out the speed and distance sums by using examples from football and the speed and the distance of the ball that Beckam kicked to the goal. This is part of the GBP 4 million campaign to make mathematics more interesting for children.
Very interesting!! I am all for any effort that makes these speed sums interesting for children.
I have traumatic memories of speed related sums from my school days that have left me permanently scarred. There were this particular genre of sums where the tap was filling a tank at a certain rate of x litres per second and there was this horrible person who was draining the water at the rate of y litres per second and we had to calculate how much time it would take for the tank of a certain capacity to be filled. Every time I am faced with a situation of water scarcity, I have a desire to seek out these water drainers and decapitate them - for spoilng my arithmetic classes as well as being the single large cause of all the global water problem.

My math teacher had a particular penchant for making our lives miserable with such problems. Another of her favourites was:
The population of town A is 4800 more than town B. If 3100 people move from town B to town A, the population in town A will be 11 times that of town B. Find the original total population of the two towns.
Faced with this problem, some of my wizard colleagues would plunge into the problem and be ready in a minute with the answer and as a bonus huge smiles. While my mind would want more data such as "why were they migrating?" "was there an epidemic?' "in which case, what about the reduction in population because of the people dying?" "What about births during the period of migration?" etc...But since i could not muster enough courage to ask the teacher to furnish all the required information, I scribbled the answer 976 3/4 and was sent out of class for being inattentive and trying to act smart! Our educational system kills all creativity, don't you see?

I think it is important to make a child relate these numbers and calculations to reality to evoke interest and make it seem more than mere numbers and additions and subtractions.
Imagine giving the following problem to a child of today:
You are traveling 40 Km/h over a bridge that is 4260 ft. long. How long does it take to cross the bridge?
Wouldn't a smart child in bangalore immediately wonder about other dependencies such as traffic jams? Isn't unfair to let the child out into the big bad world thinking that distance and speed are the only factors involved in assessing the time required to travel between point A to point B.After all , is it not the primary goal of education to prepare a child for the world?
We need to make sums sound more real and true to life to see the real life application.
Sometimes you wonder if mathematicians are people who are so absorbed in numbers that they forget the human element to life. take this problem for example:
Two trains 200 miles apart are moving toward each other; each one is going at a speed of 50 miles per hour. A fly starting on the front of one of them flies back and forth between them at a rate of 75 miles per hour. It does this until the trains collide and crush the fly to death. What is the total distance the fly has flown?

Excuse me, we are talking of a major collision here causing a few hundred deaths perhaps. Who cares about the distance the fly has flown? Sympathetic though I am to the preservation of the earth's fauna, I think that hyperactive, maniacal freak of a fly deserved to die for running between the trains.Wonder if he caused the collision by distracting the drivers with his constant flight!

P.S.: Hehehe. there , that felt really good! My sweet revenge for all the knuckle raps that I suffered at school for being so numerically challenged.
I actually have great respect for mathematics and mathematicians - no offence intended. But I really used to find some of these sums highly amusing.
