Question

what is the distance between the surface of the water and the observation deck? 15 meters. what is the distance between the surface of the water and the microphone? 10 meters. complete the statement. the distance between two different points is? a positive number.

Explanation:

Step1: Determine distance to observation deck

The water - surface is at 0 and the observation deck is at 15. The distance is calculated as $|15 - 0|=15$ meters.

Step2: Determine distance to microphone

The water - surface is at 0 and the microphone is at - 10. The distance is calculated as $|0-(-10)| = 10$ meters.

Step3: Understand distance concept

Distance is a non - negative quantity that measures the separation between two points. By definition, the distance between two different points is always a positive number.

Answer:

1. The distance between the surface of the water and the observation deck is 15 meters.
2. The distance between the surface of the water and the microphone is 10 meters.
3. The distance between two different points is always a positive number.
