Answer 2

Mathematical Representation of Train Speeds

The speed of the passenger train is represented as a km/h, and the speed of the freight train is represented as b km/h. We are given the following options to represent certain mathematical expressions:

a) a + b b) 1750:a c) 1750:b d) 1750:(a+b)

Let's analyze each option:

a) a + b b) 1750:a c) 1750:b d) 1750:(a+b)

Based on the given options, the correct mathematical representation of the speeds of the passenger and freight trains is 1750:(a+b).

This representation indicates that the sum of the speeds of the passenger and freight trains is divided into 1750 parts.

Therefore, the correct answer is 1750:(a+b).
