It totally depends on speed at which train is moving.

If the speed of train is below 100 miles per hour the minimum distance maintained should be 4 feet.

If the speed of train is above 100 miles per hour and less than 125 miles per hour the minimum distance maintained should be  6.6 feet.(Approx)

As , when a train is moving with velocity more than this i.e above 125 miles per hour the minimum distance should be 15 feet.(Approximately)

Option (C) 15

Y=-3+1/2x
yarga [219]

Answer:

(2, - 2 )

Step-by-step explanation:

y = - 3 + \frac{1}{2} x → (1)

3x + 2y = 2 → (2)

Substitute y = - 3 + \frac{1}{2} x into (2)

3x + 2(- 3 + \frac{1}{2} x) = 2 ← distribute parenthesis and simplify left side

3x - 6 + x = 2

4x - 6 = 2 ( add 6 to both sides )

4x = 8 ( divide both sides by 4 )

x = 2

Substitute x = 2 into (1)

y = - 3 + \frac{1}{2} (2) = - 3 + 1 = - 2

solution is (2, - 2 )
