A cashier can ring up 12 items per minute. How long will it take the cashier to ring up 72 items? ​
Talja [164]

Answer:

So it will take 6 minutes to ring up 72 items.

Step-by-step explanation:

Well this seems pretty simple just have to reads the question and know what to find.

So what we know :

A cashier can ring up 12 items per minute

So :

1 minute = 12 Minutes

And we have to find :

How long for 72 items

So since we know he can do 12 in a minute and it is asking how many minutes it will take for 72 we can divide.

So :

72 / 12

=

6

So it will take 6 minutes to ring up 72 items.

I hope this helps!

If Kansas City is 108 miles away how many gallons of gas I needed to get there and then home
fenix001 [56]

Answer:

Well here's the issue...

Step-by-step explanation:

Since we have no idea what car you'll be using for the experiment, I can't tell you how many times you will have to fill er' up either. let's say you have a fuel efficient car like 27 mpg. that's highway and city combined. (34/25) And the trip is 216 miles round trip. And let's say you used 0 gallons while you were there. You would need to fill up exactly 8 times to get there and back. That's going off of 27 miles per gallon.

Hope this helps!!
