Answer #1

1 meter / 100 centimeter = 1 ; 1mile/ 1609.344 meters = 1

and 1 minute/ 60 second = 1 ; 1 hour / 60 minute = 1

So, Given 30 centimeters/ second

30 centimeters = 30 centimeters * (1 meter / 100 centimeter) * (1mile/ 1609.344 meters)

= 30/( 100*1609.344) miles

( since, cancel common terms both nominator and denominator)

= 0.000186411 miles

1 second = 1 second * ( 1minute / 60 seconds) * ( 1 hour / 60 minutes )

= 1 / ( 60*60) hours

    ( since, cancel common terms both nominator and denominator)

= 1/3600 hours = 0.0002777 hours

Now, 30 centimeters/ second =  0.000186411 miles / 0.0002777 hours = 0.671 miles / hour

Therefore, 30 centimeters/ second = 0.671 miles / hour
