Plane #1 speed: x mph
Plane #2 speed: (x+30) mph
time = time becomes
170 mi 185 mi
---------- = --------------
x x+30
Solving for x, the speed of the slower plane, we get
170x + 5100 = 185 x
5100
Then 15x = 5100, and x = ---------- (mi/hr) = 340 mph
15
The slower plane flies at 340 mph, and the faster one at 370 mph.

Answer:
1 4/11 or 1.36
Step-by-step explanation:
6/11 ÷ 2/5
6/11 x 5/2 = 30/22
30/22 > 15/11
15/11 = 1 4/11
