At the very end of a race, Boat A has a position vector of (65i + 180j)
Question:
At the very end of a race, Boat A has a position vector of (−65i + 180j) m and Boat B has a position vector of (100i + 120j) m. The finish line has a position vector of 10i km.
a. Show that Boat B is closer to the finish line than Boat A. Boat A is travelling at a constant velocity of (2.5i − 6j) m/s and Boat B is travelling at a constant velocity of (−3i − 4j) m/s.
b. Calculate the speed of each boat. Hence, or otherwise, determine the result of the race.

As a Business Management graduate from Moi University, I had the opportunity to work as a tutor for undergraduate students in the same field. This experience allowed me to apply the theoretical knowledge I had gained in a practical setting, while also honing my teaching and communication skills.
As a tutor, I was responsible for conducting tutorial sessions, grading assignments and exams, and providing feedback and support to my students. I also assisted with the preparation of course materials and collaborated with other tutors and professors to ensure consistency in teaching and assessment.
