Question

Which conversion factors are used to multiply to 18 cm/s to get meters per minute?

Answer 1

18 cm/s = 18cm/s * 1m/100cm = (18/100) m/s
(notice how the units cancel out, and 1m/100cm = 1 so we're not changing anything)

(18/100) m/s = (18/100) m/s * 60s/1min (also = 1)
Therefore we get
(1080/100) m/min = 10.8 m/min
So basically 18 *60/100 m/min

Answer 2

`(60)/(100)`

Explanation:

Here, the given expression,

18 cm per sec

That is, measure in 1 sec = 18 cm

∵ 1 minute = 60 seconds,

⇒ 1 second =
`(1)/(60)` minutes,

Also, 1 meters ( m ) = 100 centimeters ( cm ),

⇒ 1 cm =
`(1)/(100)` m,

So, the measure in
`(1)/(60)` minutes = 18×
`(1)/(100)` cm,

Thus, the measure in 1 minute =
`18* (60)/(100)` cm

Hence, the conversion factors are used to multiply to 18 cm/s to get meters per minute is
`(60)/(100)`
