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 59 s?

​d(59​)=? meters

Answer 1

340 m/s * 59 s =

Answer 2

distance = speed * time

Answer 3

since d(t) = 340t for any value of t, just replace all the t's with the desired number:

d(59) = 340*59
