Onny can read 15 pages per hour, whereas nikki can read 10 pages per hour. donny has already read 10 pages and nikki has already read 25 pages. if donny and nikki sit down to read at the same time, how long will take for donny and nikki to reach the same page count? a) 2 hours b) 2.5 hours c) 3 hours d) 4 hours

Dont be afraid to read this, i explain it without using Mathematical Jargon, and its simple to understand.

It says Donny has already read Ten Pages, and Nikki has already read 25 pages.

If Nikki and Donny sat down to read in front of you, right now, for 5 hours to read from where they left off, how many hours would it take for Donny to catch up to Nikki?

You have 4 possible answers given, which is nice:

2
2.5
3
and 4

Lets start with A:

In two hours, will Nikki and Donny be at the same page in the book?

If donny reads 15 pages per hour, and its been two hours:

He is at page forty, keeping in mind that he started at page 10.

If Nikki reads 10 pages per hour, and its been 2 hours:

She is at page 45, keeping in mind that she started at page 25.

So its not A, because Nikki is at page 45, but donny is still at 40.

It would be too much If I explained the remaining three, so lets JUST do C.

I choose C, because if at 3 hours Donny still hasn't passed Nikki, then we will know it is D. If Donny HAS already passed Nikki, we will know it is B. If C is right though, then we have our answer.

SO

If donny reads 15 pages per hour, and its been 3 hours:

He is at page 55, keeping in mind that he started at page 10.

If Nikki reads 10 pages per hour, and its been 3 hours:

She is at page 55, keeping in mind that she started at page 25.

So it IS, in fact, C) 3 hours
