The speed of the wind as they travel is 105 miles per hour.
Speed is the ratio of total distance to total time taken. It is given by:
Speed = distance / time
Let s represent the speed of the wind. Hence:
(525 - s)5 = 2100
s = 105 mph

Answer:
(C)Determine the principal square root of both sides of the equation.
Step-by-step explanation:
Given: Isosceles right triangle XYZ (45°–45°–90° triangle)
To Prove: In a 45°–45°–90° triangle, the hypotenuse is times the length of each leg.
Proof:
Because triangle XYZ is a right triangle, the side lengths must satisfy the Pythagorean theorem,
Since a=b in an isosceles triangle:
Therefore, the next step is to Determine the principal square root of both sides of the equation.
To calculate the perimeter of a triangle, add the length of its sides.
x - 7 < -20
x < -20 + 7
x < -13
X = (-12, -11, -10,...)
