Question

Davey reads 45 pages in an hour. Sally reads 55 pages per hour. If Davey begins to read at 2 PM and Sally starts to read at 2:40 PM, at what time will they be reading the exact same page?

Answer 1

5.40pm

Explanation:

Davey started reading first.
This means that at 2.40pm, Davey would have read `30` pages

`(40/60 * 45)`

while Sally, `0` pages. Sally read `10` pages more than Davey per hour, this means that she will catch up with Davey at the 3rd hour after 2.40pm.

Therefore, `3` hours after 2.40pm will be 5.40pm.
