Dependence 5997

Sound travels in the air at a speed of 330 m/s. Build a table of the dependence of the distance the sound travels in a given time (for 1 to 10, one second at a time). Write the equation of the relevant dependence.

Correct answer:

s₁ =  0.33 km
s₂ =  0.66 km
s₃ =  0.99 km
s₄ =  1.32 km
s₅ =  1.65 km

Step-by-step explanation:

$$\begin{gathered} v=330/1000=\frac{33}{100}=0.33\text{km/s} \\ s=vt \\ {s}_1=v\cdot 1=0.33\cdot 1=0.33\text{km} \end{gathered}$$

$s_2=v\cdot 2=0.33\cdot 2=0.66\text{km}$

$s_3=v\cdot 3=0.33\cdot 3=0.99\text{km}$

$s_4=v\cdot 4=0.33\cdot 4=1.32\text{km}$

$s_5=v\cdot 5=0.33\cdot 5=1.65\text{km}$
