Brain Teasers
Tom & Jerry
Tom is chasing Jerry again! Jerry can run at 1 meter/sec, but Tom can run at 1.5 meter/sec.
Tom, being a stupid cat, runs into a 3 meter long sofa and takes 3 seconds to wriggle out. Jerry's mouse hole is 2 meters away from the other end of the sofa.
If Jerry runs under the sofa 1 second after Tom gets stuck, and Tom runs over the sofa to catch Jerry, will Tom catch Jerry?

If Jerry runs under the sofa 1 second after Tom gets stuck, and Tom runs over the sofa to catch Jerry, will Tom catch Jerry?
Hint
Simple MathsAnswer
Jerry beats Tom (Again!)Jerry needs to run 6 meters, (added the extra second before the sofa), while Tom has to run 9.5 meters (added the seconds taken to wriggle out)
6/1 = 6 seconds
9.5/1.5 = 6 and 1/3 seconds.
Jerry will beat Tom by half a meter or 1/3 of a second to Jerry's hole.

I can't believe it. I actually got one of the math questions right for a change. Thank you.
I suck in math usually but I got this one right, thanks for a good quiz
Cool.
If Tom is chasing Jerry, how come het gets to the sofa before Jerry? I don't get the situation.
If you raised the speeds and distances by one order of magnitude, and changed the players to vehicles, you would have a typical problem for the civil Practice of Engineering exam.
I used to hate these things when I was a high school kid. Then, one day I had an epiphany wherein I suddenly realized they are only logic problems. Now I love them. Go figure.

good idea for a teaser, but as Jimbo pointed out, tom gets to the sofa first.
if you say that jerry beats tom by half a meter after 6 seconds :
tom jerry
6sec .5 0 meters away from hole
5sec 2(end of sofa) 1
4sec 3.5 2
3sec 5 3
2sec 5 4
1sec 5 5
0sec 5(stucked - sofa) 6
it only means that tom got stuck in the sofa even if jerry is still 1 meter away from the sofa.
i liked the idea, but...

i liked the idea, but...
at the start tom is stucked in the sofa 5m away from the hole.
after 1 sec., tom is still stucked (1st second), while jerry is 5m away.
after 2 secs., tom is still stucked (2nd second), while jerry is 4m away.
after 3 3sec., tom is still stucked (3rd second), while jerry is 3m away.
after 4 secs., tom is 3.5m away from the hole(middle of sofa), while jerry is 2m away.
after 5 secs., tom is 2m away from the hole(end of sofa), while jerry is 1m away.
after 6 secs., tom is .5m away from the hole, while jerry is already in the hole.
after 1 sec., tom is still stucked (1st second), while jerry is 5m away.
after 2 secs., tom is still stucked (2nd second), while jerry is 4m away.
after 3 3sec., tom is still stucked (3rd second), while jerry is 3m away.
after 4 secs., tom is 3.5m away from the hole(middle of sofa), while jerry is 2m away.
after 5 secs., tom is 2m away from the hole(end of sofa), while jerry is 1m away.
after 6 secs., tom is .5m away from the hole, while jerry is already in the hole.
I got it right! And I didn't even solved for it . And btw for you guys that are complaining about the 1st-on-sofa thingy, you know how bias the cartoon is, so what do you expect in this teaser? lmao
