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 ;)

Thanks
