Answer:
60 km/s
step-step wise explaination:
60 kilometers / 60 minutes
= 1 kilometer / minute
as we know to convert kilometer / min we should multiply 60 to speed value
therefore, (1×60/ 1) km/hr=60 km/ hr
if you want to know why 60 multiplied with it then read this
1 km/min to km/hr
1 minute = 1/60 hour
so, for converting minute to hour we multiply 1/60
when it goes to top then it multiplied
I know it's little complicated let see it by equation
1 km/min = (1 / 1×1/60) km/h
=(1 / 1/60) km/hr
= 60 km/hr
( note there is no change in km so it remains without multiplied)
