A train is traveling at a speed of 90 miles per hour (mph). The engineer reduces the train's speed by 40% before entering the town of Plymouth. She then increases the train's speed by 50% as it leaves Plymouth. What is the new speed of the train after it leaves Plymouth?

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
