Answer:

Step-by-step explanation:
THIS is the answer if the equation looks like this. 
Answer:
The time the two planes will meet is 1.43 hours
Step-by-step explanation:
Given;
speed of the first plane in positive direction, = 40 mph
speed of the second plane in negative direction(opposite direction) = -100 mph
distance between the two planes = 200 miles
Let the time the two planes will meet = t
the position of the first plane at this time "t" = 40t
the position of the second plane at this time "t" = -100t
(40t)>--------------------------------<(-100t), this space between them is 200 miles.
Thus, the difference in the distance they traveled before meeting should be equal to 200 miles.
40t - (-100t) = 200
40t + 100t = 200
140t = 200
t = 200 / 140
t = 1.43 hours
Therefore, the time the two planes will meet is 1.43 hours
10.5^2 + 20.8^2 = 110.25 + 432.64 = 542.89
23.3^2 = 542.89
Right triangle
------------------------
20.1^2 = 524.41
6^2 + 20.1^2 = 36 + 404.01 = 440.01
Not a right triangle
