The distance reported is 510 m
Time of shot one = t1 = 2 sec (Given)
Time of shot two = t2 = 3.5 sec (Given)
Speed of sound in air = 340m/s
Time difference between the sound of two shots = t2 - t1
= 3.5 - 2 = 1.5
Distance between two ranks = Time Difference × Speed of sound
= 1.5 × 340
= 510m
Therefore, the distance reported is 510 m
