PLEASE GIVE A EXPLINATION A plane traveled 400 miles to London and back. The trip there was with the wind. It took 4 hours. The trip back was into the wind. The trip back took 5 hours. Find the speed of the plane
in still air and the speed of the wind.

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
