Answer:

300 km

Step-by-step explanation:

3 hours and 45 minutes = 3\frac{3}{4}

Speed = 80 km per hour.

80 × 3 = 240 km

80 × \frac{3}{4} = 60

240 + 60 = 300

the stairway to a cellar has a slope of -4/3, and the cellar is 2m below the ground. the equation y=-4/3x-2 models the stairway.
8_murik_8 [283]

Shown below

<h2>Explanation:</h2>

The stairway to a cellar has a slope of -4/3, that is:

m=-\frac{4}{3}

On the other hand, the cellar is 2m below the ground. In other words:

y-intercept: \\ \\ b=-2

So this can be modeled by the equation of the line:

y=-\frac{4}{3}x-2

The line has a y-intercept at point (0, -2) and as x increases 3 units y decreases 4 units. So:

x=3 \\ \\ y=-\frac{4}{3}(3)-2=-6 \\ \\ (3,-6) \ is \ also \ a \ point \ on \ the \ line

Finally, let's draw a line that passes through:

(0,-2) \ and \ (3,-6)

By using graphing tool, we get the line shown below.
