at a maximum speed an airplane travels 2100 miles against the wind in 6 hours. Flying with the wind, the plane travel the same d

Dafna11 [192]

Let x be the maximum speed of the plane and y be the speed of the wind

***Note: D = r*t or r = D/t***

x +y = 525mph |2100mi/4hr = 525mph

x -y = 350mph |2100mi/6hr = 350mph

2x = 875

x = 437.5mph, speed of plane. Wind speed is 87.5

How do I solve this?

IF:
|1/2.x -2/3.y = 7 and
|a.x - 8.y = -1

have no solution, that means these 2 linear equations ARE PARALLEL (since they can never meet). Reminder: 2 equations are parallel if they have the same coefficient , so let write each of the equation in the normal form:

a)1/2.x -2/3.y = 7→ -2/3.y = -1/2.x + 7 → y = 3/4.x - 21/2

b) a.x - 8.y = -1 → - 8.y = -a.x - 1 → y= a/8.x + 1

a) and b) are // if (3/4) = (a/8), [the 2 coefficient OR the 2 slopes)
a/8 = 3/4 → a = 24/4 and a = 6 (Answer D)
