Question: An off-roader explores the open desert in her Hummer. First she drives 25 degrees west of north with a speed of 7.0km/h for 15 minutes, then due east with a speed of 11km/h for 7.5 minutes. She completes the final leg of her trip in 22 minutes.
Part I: What is the direction and speed of travel on the final leg? (Assume her speed is constant on each leg and that she returns to her starting point at the end of the final leg).
Part II: What's the velocity in km/h?
