Question

A cyclist moving in a straight road and covers 2 km distance with speed 4 m/s and 4 km distance with speed 3 m/s. The average speed and average velocity of particle is​

Answer 1

Answer:

3.27m/s

Explanation:

avg speed = total distance / total time

d1=2km=2000m

d2=4km= 4000m

total distance= 2000+4000= 6000

time= distance/speed

t1= 2000/4=500s

t2= 4000/3= 1333.3

total time= 500+1333.3= 1833.3

avg speed= 6000/1833.3=3.27m/s
