Answer:

Explanation:

given data= 34.2 m/s

we have to convert it into km/s

as we know that

1 km=1000 m

so 1 m= 1/1000 =0.001 km

now we know that 1 min=60 sec

                              so 1 sec=1/60= 0.016 min

therefore  

34.2m/s = 34.2*m/sec =34.2*0.001 km /0.016 min

so 34.2 m/s =2.1 km/min
