4. Jim Nazium is walking from lunch to his PE class. He exits the lunchroom and walks 48 m west. He then turns and walks 60 m north down the hallway leading to the locker
room. Determine the magnitude and direction of Jim's resultant displacement.

Two students, each riding bicycles, start from the same apartment building and ride to the same building on campus, but each takes a different route. the first student rides 1100 m due east and then turns due north and travels another 1430 m before arriving at the destination. the second student heads due north for 1930 m and then turns and heads directly toward the destination. at the turning point, how far is the second student from the destination?
