@thekre8or

anonymous · Answer

5 meters per second = 0.005 kilometers per second 
so multiply 0.005 by 3600 
then multiply your answer by the three and dont round

anonymous · Answer

and that should be kilometers in 3 hours

anonymous · Answer

when i solved it was 54 kilometers

anonymous · Answer

@thekre8or 0.005 * 3600 is 18 so that is the rate km per hour?

anonymous · Answer

yes

xapproachesinfinity · Answer

just do this 1k= 1000 meter
so 1meter=1/1000
1h=3600s
1 s=1/3600
so 5 m/s=(5/1000)x3600 k/h

anonymous · Answer

the multiply by 3 and u should get 54

xapproachesinfinity · Answer

always try to do proportion dealing with such problem
we have rate of 18 km in 1 hour
18km=1hour
x=3hours
so x=3x18=54 km
