Find an Equivalent Rate

The video tutorial explains how to solve a standardized math test question by identifying an equivalent rate. It starts with a given rate of Robin reading 5 pages in 4 minutes and asks how long it will take her to read 200 pages. The solution involves setting up an equivalent ratio and calculating the time required, which is determined to be 160 minutes.

What is the main objective of the problem discussed in the video?

• To find out how many pages are in Robin's book.

• To calculate the number of books Robin can read in a day.

• To determine the total number of minutes Robin will take to read 200 pages.

• To find out how many pages Robin can read in 4 minutes.

What is the given reading rate of Robin?

• 4 pages in 5 minutes

• 10 pages in 8 minutes

• 5 pages in 4 minutes

• 8 pages in 10 minutes

What mathematical concept is used to solve the problem of finding the time to read 200 pages?

• Addition

• Multiplication

• Subtraction

• Equivalent Ratios

How do you calculate the number of minutes it takes to read 200 pages?

• Divide 200 by 5 and multiply by 4

• Multiply 5 by 40 and 4 by 40

• Add 5 and 4, then multiply by 40

• Subtract 4 from 200 and divide by 5

What is the total time in minutes Robin will take to read 200 pages?

• 160 minutes

• 170 minutes

• 180 minutes

• 150 minutes
