Question

if you do 30 sit ups in 5 mines how many sit ups will you do in 9 minutes

Answer 1

To find out how many sit-ups you can do in 9 minutes, we first need to determine your rate of sit-ups per minute. If you do 30 sit-ups in 5 minutes, we can calculate your rate as follows:

\[
\text{Rate} = \frac{30 \text{ sit-ups}}{5 \text{ minutes}} = 6 \text{ sit-ups per minute}
\]

Now, to find out how many sit-ups you can do in 9 minutes, we multiply your rate by the number of minutes:

\[
\text{Sit-ups in 9 minutes} = 6 \text{ sit-ups/minute} \times 9 \text{ minutes} = 54 \text{ sit-ups}
\]

So, you would do 54 sit-ups in 9 minutes.

Answer 2

if you read 20 pages in 25 minutes how many pages will you read in 45 minutes

Answer 3

To determine how many pages you can read in 45 minutes, we first need to find your reading rate. If you read 20 pages in 25 minutes, we can calculate your rate of pages per minute as follows:

\[
\text{Rate} = \frac{20 \text{ pages}}{25 \text{ minutes}} = 0.8 \text{ pages per minute}
\]

Now, to find out how many pages you can read in 45 minutes, we multiply your reading rate by the number of minutes:

\[
\text{Pages in 45 minutes} = 0.8 \text{ pages/minute} \times 45 \text{ minutes} = 36 \text{ pages}
\]

So, you would read 36 pages in 45 minutes.
