Gabriele enters an east-w straight bike path at the 3.0-km mark and rides w at a constant speed of 8.0 m/s. At the same time, Xena rides east from the1.0-km mark at a constant speed of 6.0 m/s.
1. Write function x(t) that describe the position of Gabriele as a function of time with respect to Earth.
2. Write function x(t) that describe the position of Xena as a function of time with respect to Earth.
3. Where do they meet each other?
4. Write a function x(t) that describes Xena's motion with respect to Gabriele.
