HERE IS YOUR ANSWER
___________________

30min=18km
60min=36km
SO 36km/h

30min =1800sec
30min=18km
1800sec=18km
18/1800
0.01km /sec

Answer 2

Hey friend here's an answer for your question....

Time = 30min = 30/60= 1/2 hr
Distance = 18km
Speed = distance/ time
=> 18/1/2 = 18*2/1
=> 36 km/hr

speed in km/sec

Time = 30min = 30*60 = 1800sec
Distance = 18km
Speed = distance/time
=> 18/ 1800
=> 1/100 km/sec or
0.01 km/sec

I think this is your answer hope helps.
