A submarine is running at a depth of 235 ft underwater. It changes course and rises 101 ft. What is the change in elevation?

The change in elevation is -134 ft

Step-by-step explanation:

Given;

initial depth of the submarine, d₁ = 235 ft

final depth of the submarine, d₂ = 101 ft

The change in the elevation of the submarine is given by;

Δd = d₂ - d₁

Δd = 101 ft - 235 ft

Δd = -134 ft

The change in elevation is negative because the submarine is moving closer to the surface.

Therefore, the change in elevation is -134 ft

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
