Question

if sound travels 1,700 meters in 5 seconds, what is its speed? *
340 m/s

Explanation:

Step1: Convert distance from miles to km

The distance from the sun to the earth is $d = 93000000\times1.609$ km.
$d=93000000\times1.609 = 149637000$ km.

Step2: Calculate time in seconds

We know that speed $v = 300000$ km/s, and from the formula $t=\frac{d}{v}$, we have $t=\frac{149637000}{300000}=498.79$ s.

Step3: Convert time from seconds to minutes

Since 1 minute = 60 seconds, then $t_{min}=\frac{498.79}{60}\approx8.31$ minutes.

for second - question:

Step1: Use speed formula

The speed formula is $v=\frac{s}{t}$, where $s = 100$ m and $t = 20$ s.
$v=\frac{100}{20}=5$ m/s.

for third - question:

Step1: Use distance formula

The distance formula is $s=v\times t$, where $v = 3$ m/s and $t = 15$ s.
$s=3\times15 = 45$ m.

Answer:

$8.31$ minutes
