A bicycle travels 6.20 km due east in 0.540 h, then 7.60 km at 15.0° east of north in 0.600 h, and finally another 6.20 km due east in 0.540 h to reach its destination. The time lost in turning is negligible. Assume that east is in the +x-direction and north is in the +y-direction. What is the magnitude of the average velocity for the entire trip?
