Question

when a body covers first one third distance with speed 1 m/s the second one thred distance with 2m/s annd last one thired distance with 3m/s find avg.speed

Answer 1

Answer:

Explanation:

11/6m/s (pardon any calculation mistakes)

Explanation:

avg speed = total dis/total time

so total distance = X

t1 = (1/3x)/1

t2=(1/3x)/2

t3=(1/3x)/3

because speeds are 1m/s, 2m/s and 3m/s resp.

therefore avg speed =

(t1+t2+t3)/x

=11/6m/s

Answer 2

Answer:

2 m/s

Explanation:

average:1+2+3/3

=6/3 m/s

=2 m/s
