kenny6666 [7]

Answer:

65 miles

Step-by-step explanation:

There are two simultaneous equations . Remeber that v=d/t, 1hour = 60 minutes.

1. 40 = (d+15)/(t+0.5)

2. 50 = d/t

solving: d= 25 miles and t=0.5 hours.

The distance traveled is:

D=d+d+15

D=65 miles

Please explain also! I am not here just to get answers, I am here to understand. Thank you!
kolezko [41]

To help solve this, we need to use the slope formula.

(y2 - y1) / (x2 - x1). We get these values by picking two points on a line.

For JL, we will pick points (-5, -3) and (-2, -4).

y1 = -4

y2 = -3

x1 = -2

x2 = -5.

Let's plug these into our formula.

(-3) - (-4) / (-5) - (-2) = -1/3

For LN, we will pick points (-2, -4) and (7, -7).

y1 = -7

y2 = -4

x1 = 7

x2 = -2.

Lets plug these values into our equation.

(-4) - (-7) / (-2) - (7) = -1/3

Therefore,

(-3) - (-4) / (-5) - (-2) = (-4) - (-7) / (-2) - (7)

The correct answer is G.
