Given 1.52s, start there and apply converters

1.52 s (343m/1sec) = 521.36 m

now divide by 2: 260.68m ((echo is 2 way))

round to 3 sigfigs: 261m <<<<

Given,

Time (t) = 1.52secSpeed of sound (v) = 343m/secDistance (d) = ?We know that:-Speed (v) = distance (d) / time (t)Distance (d) = speed (v) x time (t)= 343m/sec x 1.52sec= 521.36m∴ distance (d) = 521.36m.

(343 x 1.52)/2 = 260.68 meters. The other answers give the distance the sound travelled to AND from the hill
