A turtle and a rabbit are in a race to see who is first to reach a point 100 feet away. The turtle travels at
constant speed of 20 feet per minute for the entire
100 feet. The rabbit travels at a constant speed of
40 feet per minute for the first 50 feet, stops for 3
minutes, and then continues at a constant speed of
40 feet per minute for the last 50 feet. Determine
which animal won the race and by how much time.

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.
