Answer 2

Problem Analysis

We have two points that are 80 meters apart. A boy and a girl start walking towards each other from these points. The boy walks 35 meters, and the girl walks 30 meters. We need to determine how many meters they have left to meet each other.

Solution

To find the remaining distance, we can subtract the sum of the distances covered by the boy and the girl from the total distance between the points.

The total distance between the points is 80 meters. The boy has covered 35 meters, and the girl has covered 30 meters. Therefore, the remaining distance can be calculated as:

Remaining distance = Total distance - (Distance covered by the boy + Distance covered by the girl)

Substituting the values:

Remaining distance = 80 - (35 + 30)

Simplifying the expression:

Remaining distance = 80 - 65

Calculating the remaining distance:

Remaining distance = 15 meters

Therefore, the boy and the girl have 15 meters left to meet each other.

Answer

The boy and the girl have 15 meters left to meet each other.
