Answer

60 s / 1 m

Explanation

18 cm/s means 18 cm in 1 second.

When converting 18 cm/s into meters per minute, you need to convert 18 cm into meters and 1 second into minute.

18 cm = 18/100 meters.

1 second = 1/60 minutes.

18/100 meters per 1/60 minutes

18/100÷1/60 = 18/100 ×60/1

= 18 ×(60/100) meters per minute

The factor is 60s/100cm, which is equivant to 60s/1m

Answer:  The multiplication factor which use to convert cm/s to meter/minute is 60/100 or 3/5.

Step-by-step explanation:

Here the given expression, 18 cm/s

Since, we know that 1 meter= 100 cm ⇒ 1 cm = 1/100 meter

And, 1 minute = 60 second ⇒ 1 second = 1/60 minute

Thus, 18 cm/s=  [tex]\frac{18\times 1/100}{1/60}[/tex] meter/ minute

⇒ 18 cm/s = [tex]18\times \frac{60}{100}[/tex]= [tex]18\times \frac{3}{5}[/tex]

⇒ 18 cm/s = 10.8 meter/min

Therefore, we need to multiply 3/5 to change cm/s to meter/sec.
