Let v be the speed of the slower plane in mph.
Then the speed of the faster plane will be (v + 55) mph.
the closing speed of the two planes is the sum of their speeds:
v + v + 55 = 2v + 55
Cross-multiplying, we get:
6v + 165 = 1965
6v = 1800
v = 300
The speeds of the planes are 300 mph and 355 mph.

Hello,
(3+2i)z+1-2i=2iz-2+i
<==>(3+2i-2i)z=-2+i-1+2i
<==>3z=3(-1+i)
<==>z=-1+i
