Question

I went from my house to the playground 300 metres away in 600 seconds I ran back and reached in 1200 seconds what was my average speed​

Answer 1

Answer:

Avg speed = total distance/total time

converting meter into km

300/1000=0.3km

avg speed = (0.3+0.3)/12

avg speed = 0.6/12

=0.05km/min

Answer 2

Answer:

av.speed=total distance/total Time

=300+300/600+1200

=600/1800

=3m/s
