Answer:

Step-by-step explanation:

-2x - y = -3

y = -3x + 2

-2x - (-3x + 2) = -3

-2x + 3x - 2 = -3

x = -1

y = -3*-1 + 2 = 5

A submarine left hawaii and travels east at an average speed of 10 mph. An aircraft. Carrier left at the same time and traveled

Rina8888 [55]

Answer:

10 hours

Step-by-step explanation:

Given:

Average speed of submarine = 10 mph

Speed of carrier in the opposite direction = 20 mph

Distance between the submarine and carrier = 300 mi

To find:

The time taken so that the distance between them is 300 mi ?

Solution:

The relative speed when they are traveling in opposite direction = 10+20 = 30 mph

Formula:

$\text{Time }=\dfrac{\text{Distance Traveled}}{\text{Speed}}$

$\text{Time }= \dfrac{300}{30} = \bold{10\ hours}$

So, the answer is 10 hours.
