Seth starts reading at 4:30 pm and reads 30 pages an hour. Jamaal starts reading at 5:20 pm and reads 40 pages an hour. At what time will they be reading the same page if they both began on page 1?

7:50

Step-by-step explanation:

The difference between the starting times is, 5:20 - 4:30, 50 minutes.

Since Seth reads 30 pages an hour, he also reads 1 page every 2 minutes or 3 pages every 6 minutes. Also, since Jamaal reads 40 pages an hour, he also reads 4 pages every 6 minutes. We now know that every 6 minutes, Jamaal reads 1 more page than Seth.

Seth started at 4:30, meaning by the time Jamaal starts reading, Seth has already read 25 pages.

To catch up Jamaal needs to read for 25 * 6 minutes, 150 minutes.

If we add 2 and a half hours to 5:20, we get 7:50.

answer: 5100 just subtract
