Answer:
I think that it would be 
cm
Step-by-step explanation:
8 x 7 = 56
56/2 = 28
What exactly is the question here?
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.
Well, first you multiply 22×3 and then add the answer by 3!. whole times denominator plus numerator!
