Susan can read 72 words in One-third of a minute. Which statement is correct? She can read 24 words per minute, because 72 divided by One-third is equal to 24. She can read 24 words per minute, because 72 times One-third is equal to 24. She can read 216 words per minute, because 72 divided by One-third is equal to 216. She can read 216 words per minute, because 72 times One-third is equal to 216.

Answers

Answer:

The answer is

"She can read 216 words per minute because 72 divided by One-third is equal to 216."

Step-by-step explanation:

Given the statement

Susan can read 72 words in One-third of a minute ....pause

Whats is one-third of a minute

it is expressed as 1/3*60=20sec

so Susan can read 72 words in 20 second

this means that in a minute she can read

72+72+72 words= 216 word since 20sec*3 is 1 minute

alternatively

=(72)/((1)/(3) )

we then multiply 73 with the inverse of the denominator

=72*(3)/(1)

=216 words

Density = 0.8 g/cm³

Volume = 9000 cm³

D = m / V

0.8 = m / 9000

m = 0.8 x 9000

m = 7200 g
