Question

If the straight-line distance from her home to the university is 10. 3 km in a direction 25. 0° south of east, what was her average velocity in km/h?.

Answer 1

The average velocity in km/h is: 34.3km/hr

What is average velocity?

Average velocity refers to speed at which the time intervals (t) change in position or displacement happens, divided by the change in position or displacement (x).

=> Average velocity = $\frac{displacement}{time}$

Now,

The time taken is missing in the question; the time taken = 18 mins = $\frac{18}{60}$ hours.

The distance of her home to the university = 10.3 km

As, average velocity = $\frac{displacement}{time}$

=> Velocity = $\frac{10.3\times60}{18}$ = 34.3 km/hr

Hence, the average velocity = 34.3 km/hr
