You HEAR the explosion after
(5,400 ft) x (1 meter / 3.28 ft) x (1 sec / 343 meters) = 4.80 seconds.
The speed of light is 299,792,458 m/s.

Explanation:
This problem bothers on application of the expression for motion emf which is expressed as
where B= magnetic field in Tesla
l= length of the conductor
v= speed of conductor
Given data
l= 2 meters
v= 6 m/s
B= 5 Tesla
Applying the formula we have
