The time interval between seeing the flash of lightning and crack of thunder is 7s. Of tje velocity of sound os 340ms? find the height of cloud

Time (t) = 7 seconds
Initial velocity (U) = 340m/s
Final velocity (V) = 0 m/s
Acceleration (a) = ?
Let the height of the cloud be S.
As referring to the formula of Position-Time relation ( S = Ut + 1/2 at^2 )
Therefore a = V - U/t, a = 0 - 340/7 = -48.57142857142857
Therefore S = Ut + 1/2 at^2, S = 340*7 + 1/2*-48.57142857142857*7*7 = -2,393,999,997,640.49958
