What is your velocity?
O 0 m/s
O +3 m/s
O +4 m/s
O +17 m/s

Respuesta :

Answer: +17 m/s ==> option 4

Explanation:

4 km + 8 km + 8.9 km=

12+8.9=20.9 km

1 km=1000 m

20.9 km * 1000 m/1 km=

20.9 * 1000/1=

20.9 * 1000=20900 m

1 min = 60 sec

20 min * 60 sec/1 min=

20*60/1=

20*60=1200 minutes

20900/1200=

209/12=17.4

17.4=+17 m/s ==> option 4
