Question

In a helicopter, Ronny is 200 feet above sea level, and in a submarine, Daniel is 150 feet below sea level. Daniel and Ronny are feet apart from each other.

Answer 1

Below the sea level, distances are represented by negative numbers and above the sea level distances are represented by positive numbers.

$\therefore$ Distance between Ronny and Daniel $=200+|-150|$

Step 1: Write absolute value of both integers.
|200|=200
|-150|=150

Step 2: Add both the absolute values.
$200+150=350$

Ronny is $350\text{feet}$ away from Danial.
