Answer 3

Solution:

To solve this problem, we can use a system of equations to represent the given information and then solve for the number of pages Peter read on the first day.

Let's denote: - x as the number of pages Peter read on the first day. - 3x as the number of pages Peter read on the second day.

According to the given information, Peter read a total of 172 pages over two days. This can be represented by the equation: x + 3x = 172

Solving for x: 4x = 172 x = 43

So, Peter read 43 pages on the first day.

Answer:

Peter read 43 pages on the first day.
