Sound travels about 340 m/s. The function d(t) = 340t gives the distance d(t), in meters, that sound travels in t seconds. How far does sound travel in 56 s?
To find the distance that sound travels in 56 seconds, we can substitute t = 56 into the given function d(t) = 340t:
d(t) = 340t
d(56) = 340(56)
d(56) = 19040
Therefore, sound travels 19040 meters in 56 seconds.
