a 343 meters per second (m/s)

b 306.083 meters per second (m/s)

c 1450 to 1498 meters per second

d 5,960 meters per second

Explanation:

a) speed of sound In air at ground level (20° C)

= 343 meters per second (m/s)

b) speed of sound for airplane (-40° C)

= 306.083 meters per second (m/s)

c) speed of sound In water

= Water (distilled) range from 1450 to 1498 meters per second,

and Water (sea) 1531 meters per second

d) speed of sound In steel

= 5,960 meters per second
