sound travels about 340 m/s. The function d(t)=340t give distance d(t), in meter, that sound travels in t seconds. How far does sound travel in 56s?

To find the distance sound travels in 56 seconds, we substitute t = 56 into the function d(t) = 340t:

d(56) = 340 × 56
d(56) = 19040

Therefore, sound travels 19,040 meters in 56 seconds.
