I believe it’s 12 minutes since the since the time is unknown, you set it up as x/20+x/30 since you know that they are being added. Filling up the canteen is 1 because you want it full all the way so you find the common denominator and solve for the x which is 12

Find the scale factor of ABC to MNO.
timofeeve [1]

Answer:

6/5

Step-by-step explanation:

The scale factor can be obtained by simply finding the ratio of the lenght of the side of one shape to the length of the same side of the other shape.

Thus, we can obtain the scale factor that will take us from △ABC to △MNO as illustrated below:

Original Length BC = 15 in

New Length NO = 18 in

Scale factor =?

Scale factor = New lenght NO / Original length BC

Scale factor = 18 / 15

Scale factor = 6/5

Therefore, the scale factor that will take us from △ABC to △MNO is 6/5.

When you convert fron pints to quarts why do you divide
user100 [1]
We divide when converting pints to quarts because pints are smaller units of measurements than quarts, so when converting pints to quarts, our answer will be getting smaller. This is because 2 pints= 1 quart, so since we are trying to find the amount of quarts that the pints can make up, we will always divide the pints by 2. (since 2 pints= 1 quart)
