Answer 1

Answer:

Your answer is 24km/hr

PLease mark me as brainlist

Explanation:

Let the dist. be x

dist. while going = dist while returning

time = dist./speed

so, time while going = x/20

time while coming =x/30

total time= x/20+x/30

=(3x+2x)/60

=5x/60

=x/12

total dist.= 2x

avg. speed = total dist./total speed

=2x*12/x

=24km/hr

Answer 2

Explanation:

Average speed= total distance/total time taken

20+30=x/2

50=x/2

x=100
