It takes 3 minutes to fill a 60 l bathing pool. what is the average rate in liters per hour

1200 liters per hour.

Step-by-step explanation:

Given : It takes 3 minutes to fill a 60 L bathing pool.

i.e. capacity of pool = 60 liters

Time taken to fill a 60 L bathing pool= 3 minutes

Then, the average rate in liters per minutes will be :-

Since 1 hour = 60 minutes

i.e. 1 minute=

Then, Average rate in liter per hour =

Hence, the average rate = 1200 liters per hour.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
