Question

A bus travels at first 40km with a velocity of 60km/h and next 60km with a velocity of 120km/h. Find average speed and average velocity

Answer 1

Answer:

u = 60 km/h

v = 120 km/h

distance  traveled in first interval = 40 km

distance  traveled in second interval = 60 km

average speed = $\frac{120-60}{60-40}$ = $\frac{60}{20}$ = 3 km/h

average velocity = $\frac{v-u}{2}$ = $\frac{120-60}{2}$ = 30 km/h
