The speed of sound at sea level is 340 m/s. alan is standing 255m from his friend, paul. if alan shouts to paul how long willi it take before paul hears him will give

0.75 s

Step-by-step explanation:

The relation among distance (d), speed (s), and time (t) is

d = st     Divide both sides by s and transpose

t = d/s

Data:

s = 340 m/s

d = 255 m

Calculation:

t = 255/340

t = 0.75 s

It will take 0.75 s until Paul hears Alan.

step-by-step explanation:

i could only see the first page. the other pages were blurry. ; -;

x hot dogs for 2$, y drinks for 3$. 29 items and total 70

2x+3y=70

x+y=29

if x=17and y=12

2(17)+3(12)=70

34+36=70
