Raina can read 39 pages in
30 minutes. Robert can
read 60 pages in 50
minutes. If they both begin
reading the same 312-page
book, how many more
minutes will Robert take to
finish the book?

Answers

Answer 1

Answer:

Step-by-step explanation:

Raina takes 30 minutes for 39 pages. So that means she read 1.3 pages per minute. Then we take 312 divided by 1.3 = 240 minutes, she needs to finish the book.

Robert takes 50 minutes for 60 pages. So that means he read 1.2 pages per minute. Then we take 312 divided by 1.2 = 260 minutes.

260mins - 240mins = 20 mins

So Robert will need 20 minutes to finish the book.

All students in Ridgewood Junior High School either get their lunch in the school cafeteria or brought it from home on Tuesday. 2% of students brought their lunch. 50 students brought their lunch. How many students in total are in Ridgewood Junior High School?
Multiply/scale up to solve.

Answers

Answer:

2% can be written as 0.02
So the total amount of kids multiplied by 0.02 is 50

Then 50 divided by 0.02 is 2500 which is the total amount of kids at the school.

Hope this helps!
