Question

Cars travels 22km south 12 km west & 14 km
North in half hour. Calculate average speed and velocity. ​

Answer 1

Answer:

Speed = 96 km/h

Velocity = 28.84 km/h

Explanation:

Total distance travelled = 48 km

Total displacement = 14.42 km (approx)

Time Taken = Half-an-hour = 0.5 hr

Speed = $\frac{Distance}{Time} = \frac{48}{0.5} = \frac{480}{5}$ = 96 km/h

Velocity = $\frac{Displacement}{Time} = \frac{14.42}{0.5} = \frac{1442}{50}$ = 28.84 km/h

Hope this helps.....
