Question

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 45 s?

Answer 1

Explanation:

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

How far does it travel in 45 seconds? so t = 45

time to substitute and insert the numbers in for d and t.

d (t) = 340t

d (45) = 340 (45)

d (45) = 15,300 meters per second
