Question

the war correspondent of a TV channel watches the flashes of two tanks firing at each other at the same time on a straight road ahead of him and he hears the sounds of the two shots 2 second and 3.5 second after seeing the flashes taking the speed of sound in air as 340 m/s he quickly calculates and reports the distance between the tanks and what distance did he report ​

Answer 1

The total distance between the two tanks is equal to 510m.

The two shots from the tanks are heard after 2 seconds and 3.5 seconds respectively .

The time difference between the two shots = 3.5 - 2 = 1.5 seconds

The velocity of sound in air = 340 m/s

The distance between the tanks = time difference between the shots × velocity of sound in air

= 1.5 × 340

= 510 m
