Lets use the formula $RWT=J$ to solve this, where,

"If it takes 10 seconds for 10 printers to print out 10 pages of paper" - here -

W is 10 printers, T is 10 seconds, and J is 10 pages. We can write:

$R(10)(10)=10\\R(100)=10\\R=\frac{10}{100}\\R=0.1$

"how many seconds will it take 50 printers to print out 50 pages of paper" - here we use $R=0.1$ (previously found) to figure out T.

$RWT=J\\(0.1)(50)T=50\\5T=50\\T=\frac{50}{5}\\T=10$

So it will take 10 seconds for 50 printers to print 50 pages.

Answer:

instead of just pointing out the highest speed or one speed, list all the different speeds or increasing/decreasing and the different intervals

ie for minutes 2 to 3, her speed was 30 mph . . . from minutes 6 to 8, her speed was decreasing at a constant rate of -2 mph/min
