38,000 - 18,000 = 20,000 ft
20,0000 ÷ 600
=33.3
= 33 minutes 20 seconds
Answer:
c). y + x = 0
Step-by-step explanation:
The locus is a line perpendicular to the line connecting the 2 points and passing through the centre of the line.
The mid-point of the line connecting the given points is:
(a + b + a - b)/2 , (a - b + a + b) / 2
= (a, a)
It's slope = (a + b)- (a - b) / (a - b)- (a + b)
= 2b/ -2b
= -1
So the slope of the line we want is -1/(-1) = 1.
Using the point-slope form of a line:
y - y1 = m(x - x1)
y - a = 1(x - a)
y - a = x - a
x + y = 0
