Before we get started, it is good to remember PEMDAS - the acronym that tells you the order to carry out equations.
P = parentheses
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
Knowing this, we should start by doing the equations <em>within </em>each parentheses.

So we did the addition and subtraction pieces within each group leaving us with the above equation. Now let's multiply:

20 is the answer.
A triangle is only possible if you can add any two sides and have the sum be larger than the third side. This happens with choice B, C, and D.
With choice A, we have 11+14 = 25 not larger than the third side of 25. So a straight line is possible and it's not possible to draw a triangle with these dimensions.
Answer: Choice A
note: This is using the triangle inequality theorem
Answer:
1/2 + 1/2 = 1
1/4 + 1/4 = 1/2
So you would walk 1/2 mile in 1 hour
