The graph shows that chelsea can type 175 words in minutes.

In this graph, we see Chelsea types 50 words per minutes.
To find the answer, I will use tree diagram:
50 words in 1 minute
175 words in ?minutes
Step 1:
Cross multiply
175×1=175
Step 2:
Use division
175÷50=3.5 or 3 1/2 minutes. As a result, Chelsea types 175 words in 3.5 minutes or 3 1/2 minutes. Hope it help!

As shown by the graph's first plot, Chelsea can type 50 words in one minute. With this information, it is a simple proportion:
1 X
=
50 175

Just solve 175/50 and that is your answer for minutes.

175 / 50 = 3.5
she can type 175 words in 3 and a half minutes.

If you'd want the answer you have to do 164,502,423 subtract 100,000 which all you have to do is subtract from the hundred thousands place which is in this case 500,000 so it would be 164,402,423. I hope i gave a good understanding :)
