Divide one sample of jumping jacks by each girl by their time to find the unit rate. Then compare unit rates. Recall, a unit rate is the number of jumping jacks done in one minute. Cortney does 15 jumping jacks in 1 minute in the first entry of the table. Mallory does 60 jumping jacks in 5 minutes according to a point on the graph. Divide 60/5=12. She does 12 jumping jacks per minute. Thus Cortney does 3 more per minute.

Steve reads 80 pages in 2 hours and 40 minutes. If Cassandra reads twice as fast as Steve, how long will it take her to read a 3

zlopas [31]

Answer:

Option B. 5 hours.

Step-by-step explanation:

Steve reads 80 pages in 2 hours and 40 minutes.

1 hour = 60 minutes

2 hour 40 minutes = (2 × 60) + 40 = 160 minutes

Speed of reading of Steve = $\frac{80}{160}$

= 0.5 page per minute

Cassandra reads twice as fast as Steve.

Therefore, speed of reading of Cassandra = 0.5 × 2

= 1 page per minute

Therefore, time to read 300 pages by Cassandra = 300 × 1

= 300 minutes

Now convert minutes to hours

$\frac{300}{60}$

= 5 hours

Cassandra will take 5 hours to read 300 page book.
