Rhonda bought her son an inflatable pool for the summer. It took her 20 mins to fill the pool to a depth of 6 in. What is the unit rate per minute(in per minute)

What is the unit rate per inch(mins per in)

Respuesta :

Per means one. So this asks for in one minute, and in one inch.
20 minutes = 6 inches.
So dividing by 20 gets you one minute.
1 minute = 6/20 inches
1 minute = 3/10 inches

20 minutes = 6 inches.
So dividing by 6 gets you one inch.
20/6 minutes = 1 inch
10/3 minutes = 1 inch
