Answer 1

1-весь путь
1/3-совместная скорость
1:1/3=1*3/1=3ч от начала движения
3-1=2ч-от того, как проехали 1/3

Answer 2

Problem Analysis

Two riders are traveling towards each other and have covered 1/3 of the total distance in 1 hour. We need to determine how long it will take for them to meet.

Solution

Let's denote the total distance as D. Since the riders have covered 1/3 of the distance in 1 hour, we can calculate the speed of each rider.

The combined speed of the two riders is the sum of their individual speeds. Using the formula speed = distance / time, we can calculate the time it will take for them to meet.

Calculation

The speed of each rider is D/3 (since they covered 1/3 of the distance in 1 hour).

The combined speed of the two riders is 2*(D/3).

The time it will take for them to meet is D / (2*(D/3)).

Result

Solving the equation, we get: D / (2*(D/3)) = 3/2 hours

So, the two riders will meet in 1.5 hours.
