Joanna has a big paper due. Yesterday, she started typing her hand-written draft. She typed 861 words of it and saved her work to continue later. If she types at a rate of 50 words per minute, and the paper is 1,461 words long, how much more time does she have
to spend typing?
A. 17 minutes
B. 20 minutes
C.15 minutes
D. 12 minutes

12 minutes , which agrees with answer D in the list

Step-by-step explanation:

The total length of the paper is 1461 words, she already typed 861, so she has left to type:

1461 - 861 = 600 words.

Since she types 50 words per minute, then she would need: 600/50 = 12 minutes for the rest.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

570, the answer is 570, hope it
