How many km/hr is 30 m/s?

Fyi, this is the chemistry section so

convert each

30 meters per second

kilometers per hour

1000 meters=1 kilometers

60 seconds=1 hour so

30 meters=30/1000 kilometers=3/100=0.03 kilomiters

1 second=1/60 hours

0.03 / (1/60)

make the bottom = 1

multiply the whole fraction by (60/1) / (60/1)

1.8 / (60/60) = 1.8/1=1.8km/1h

the answer is 1.8km/h
