The building is 231.7 m far away.Distance can refer to a physical length or an estimate based on other factors in physics or common use.
<h3>What is distance?</h3>
Distance is a numerical representation of the space between two objects or locations. |AB| is a symbol for the distance between two points A and B.
Given data;
Speed of sound = 331 meters per second
Time = 0.7 sec
The distance from the building is;
d=v×t
d=331 m/sec × 0.7 sec
d=231.7 m
Hence the building is 231.7 m far away.

The correct answer is: "The value of the 5 in 50.8 is 1,000 times the value of the 5 in 18.35."
Step-by-step explanation:
When numbers are considered, their position or place value matters a lot.
When a decimal number is written, moving left from the decimal point the place value increases ten times and while moving to the right the place value decreases 10 times.
Given two numbers are:
50.8 and 18.35
In order to compare the 5 in both numbers we have to find the place value of 55 in both numbers.
So,
<u>In 50.8:</u>
The place value of 5 in 50.8 is: 50
<u>In 18.35:</u>
The place value of 5 will be: 5/100
To compare the values, we will divide the larger place value by smaller place value

Hence,
The correct answer is: "The value of the 5 in 50.8 is 1,000 times the value of the 5 in 18.35."
