Sound travels about 340m/s the function d (t) = 340t gives the distance d (t) in meters that sound travel in t seconds how far doe sit travel in 49 s

D (t) = 340t ... where d (t) is the distance and t is the seconds

how far does it travel in 49 seconds ... so t = 49

time to sub

d (t) = 340t

d (49) = 340 (49)

d (49) = 16660 meters per second <===
