Lydia wrote 4.5 pages on her science report in 1 hr.What was her writing rate in pages per minute?

4.5 / 60 = 0.075 page per minute

To find Lydia's writing rate in pages per minute, we need to divide the number of pages she wrote (4.5) by the time it took her to write them (1 hour).

Step 1: Convert the time from hours to minutes. There are 60 minutes in 1 hour, so we can multiply the number of hours by 60 to get the equivalent time in minutes.

1 hour x 60 minutes per hour = 60 minutes

Step 2: Divide the number of pages by the time in minutes.

4.5 pages / 60 minutes = 0.075 pages per minute

So Lydia's writing rate is 0.075 pages per minute.
