Question

Ms. Rogers gave the class 6 minutes to read. Stephanie read 4 1/2 pages in that time. At what rate, in pages per hour did Stephanie read?

Answer 1

Stephanie read at a rate of 45 pages per hour, calculated by dividing the 4.5 pages she read by the time in hours (0.1 hour).

Step-by-step explanation:

To calculate the rate at which Stephanie read, in pages per hour, we convert the minutes into hours and then use the rate formula which is rate = distance/time. Stephanie read 4 1/2 pages in 6 minutes. Since there are 60 minutes in an hour, we first convert 6 minutes to hours by dividing by 60.

6 minutes ÷ 60 minutes/hour = 0.1 hour

Now, we calculate the reading rate in pages per hour by dividing the number of pages read by the time in hours.

Reading Rate = Number of Pages Read ÷ Time in Hours

Reading Rate = 4.5 pages ÷ 0.1 hour = 45 pages per hour

Therefore, Stephanie read at a rate of 45 pages per hour.
