An english instructor asserted that students' test grades are directly proportional to the amount of time spent studying. lisa studies 2 hr for a particular test and gets a score of 73. at this rate, how many hours would she have had to study to get a score of 92?

  about 2.521 hours

Step-by-step explanation:

To get a grade that is 92/73 times as high, she would need to study 92/73 times as long, so ...

  (92/73)·2 hours = 184/73 hours = 2 38/73 hours ≈ 2.521 hours

That's about 2 hours 31 minutes 14 seconds.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
