You hear a hammer 5 seconds after you see it move. How far away is the hammer?

The hammer is far

why?

when you heard the hammer it was after it his so when you saw it it was already up

v = speed of sound = 343 m/s

t = time taken by the sound to travel from hammer to listener = 5 sec

d = distance of hammer from the listener = ?

we know that

distance = speed x time

hence

d = v x t

inserting the above values

d = 343 x 5

d = 1715 m

hence the hammer is 1715 m away
