Question

When a person leaves his home for sightseeing by his car, the meter reads 12352 km. When he returns home after two hours the reading is 12416 km. (a) What is the average speed of the care during this period? (b) What is the average of velocity?

Answer 1

(a) Total distance covered = 12416 − 12352 = 64 km
$\therefore \mathrm{Average}\mathrm{speed}=\frac{64}{2}=32\mathrm{km}/\mathrm{h}$

(b) Because he returns to his house, the displacement is zero. So, the average velocity is zero.
