It's alright.

revlogic · Answer

Ok, we want cm/sec to become m/min.
So we need to use two ratios: 1m/100cm and 60sec/1min

Now let's multiply it out:
18 cm/sec  x 1 m/ 100 cm  x 60 sec/1 min

And don't forget to cross out all the likes units:

(18*1*60)/100

==>10.8 m/min

NO, b and c....So we need to use two ratios: 1m/100cm and 60sec/1min

revlogic · Answer

Because you want meter for your numerator and minute for your denominator
