I was in the bank today just as their wall clock turned to 10.00 am. I checked my wristwatch, it read 10.02- it occurred to me that, if I was far enough away from the bank's clock, both clocks might be correct, because the light that reached me at 10.02 would have come from 10.00.

Assuming the theory holds true, how far away from the bank's clock would I have to be for both clocks to be correct- and how long, at an average walking speed of 4mph, would it take me to reach the counter in front of the bank's clock?

Cheers ;)

You would not be able to see a clock two light minutes away. Without a calcuator, I see that 18,630,000 miles is the distance for 100 seconds. About 20% more is 3,726,000 miles. Total is 22,356,000 miles. To walk that far takes 5,589,000 hours. That's about 621 years figuring in my head. With a calculator, I can give more precise figures.

Wrong way around, methinks.
If you were 2 light-minutes away from the Bank's clock and your watch was still 2 minutes fast then your watch would show 10:04 when you saw the Bank's clock flick to 10:00

Light travels 22353887.64 miles in 2 minutes, so this is the distance you would have to be from the clock. If you sarted to walk to the clock at 4 MPH it would take you 637 years, 1 day, 3 hours and 45 minutes (maybe).

you got nice imagination..
and take my compliments:you ought to pass a letter to the world
guinness book organizers for having got a great eye that can see
clearly upto a distance of 3.6*10^10metres...

if ever your theory is correct[giggling] you must reach at the counter if your great watch and the counter clock have same
time

to the next question :
if you crawl ,sorry walk at 4 mph ,that is 1.78 m/s in the S.I.
units ,you will take 641.3 years to reach there[ if you stay alive]

i advice you to repair your watch and increase your walking speed for your own good!!!!!!!!!

sorry, mate.take it lightly.
you have a doubt you must shoot, don't think if it will be logical or not..
well done...

you have it all wrong it is not the distance you search for .l it is the speed that would alter the time for 2 minutes.

what if you syncronized your wrist watch with the one of the bank. and move away from it ...i mean really really far away....you woudl read the same time. and do not mess light that reached you before or after.
the problem becomes interesting if you move for the same distance in different time. and the observer gets differernt time readings than you -->> time travel.

WHAT WOULD BE INTERESTING IS FOR YOU TO MOVE REALLY QUICK AND MAKE YOUR CLOCK RUN SLOWER. in order to meet the bank's clock

Light travels at 299792458 metre'/second. If you travelled for 2 minutes at the speed of light - you would be 35, 975,094 km's away. Considering the Circumference of the wolrd at the equator is 40066km, There is no-where you could actually walk to to see it!

If there was a 2 minute difference either your watch or their clock was wrong, possibly both.

Refer to Einstein's Theory of Relativity.

The time would only be correct at a distance relative to you, however the time would still remain different at both end points.

It had to be due to the fact that you stepped through a time vortex 2 minutes into the future!
