We have started reading homework that has 36 pages. The first 10 pages took 5 minutes, if we continue at the same rate we will read 10 more pages every 5 minutes.
We need to determine how many pages we are reading per minute at this rate. To do that, we have to divide the number of pages we read in 5 minutes, which is 10, by the time it took us to read them, which is 5. This is done below:
At this rate, we can read 2 pages per minute.
We need to fill the table provided. We will first start with the Minutes row. We already read 10 pages and this took us 5 minutes, so we have:
Minutes: 5 |
Pages: 10 |
if we spend 5 more minutes reading, then we will read 10 more pages. So the new marking for minutes should be 5+5=10 and the one for pages should be 10+10=20. We have:
Minutes: 5 | 10 |
Pages: 10 | 20 |
We can repeat this process once again, adding 5 minutes and 10 pages. We would have read 20 + 10 = 30 pages and it took us 10 + 5 = 15 minutes. So we have:
Minutes: 5 | 10 | 15 |
Pages: 10 | 20 | 30 |
Now we can't repeat the process same process as above, because we only have 6 pages left. Luckily we calculated how many pages we can read per minute before, for every minute that passes we can read 2 pages, since we have 6 pages left, it'd
