The speed of Washington Plane is 500 mph and LA plane is 600 mph.

Step-by-step explanation:

Given :

The distance between the cities is 2700 miles.

Solution :

Let v and u are the speeds of the two planes of Washington and LA respectively.

Given that after two hours the distance between them was still 500 miles, therefore

$\rm 2v +2 u + 500 = 2700$ ---- (1)

It is also given that LA plane was 100 mph faster, so

$\rm u = 100 +v$ ---- (2)

Now put the value of u in equation (1) we get,

$\rm 2v +2(100+ v ) +500 = 2700$

$\rm 4v = 2000$

v = 500 mph

Now put the value of v in equation (2),

u = 600 mph
