Question

Реши задачу.два всадника встретились и продолжили движение в противоположных направлениях.когда 1 всадник оказался за 20 км от места встречи,2 всадник проехал 4/5 этого расстояния.на каком расстоянии друг от друга оказались всадники?

Answer 1

На 36 км. т.к.4/5 от 20 это 4 а 4 умножить на 4 ровно 16, 20 + 16=36

Answer 2

20:5*4=16 км. проехал 2 всадник 20+16=36км . проехали вместе 2 всадника

Answer 3

Problem Analysis

Two riders met and continued in opposite directions. When the first rider was 20 km from the meeting point, the second rider had covered 4/5 of this distance. We need to find the distance between the two riders.

Solution

Let's denote the distance between the two riders as D. When they met, the first rider traveled 20 km and the second rider traveled 4/5 * 20 km = 16 km.

The total distance between the two riders is the sum of the distances they traveled. Therefore, D = 20 km + 16 km.

Calculation

D = 20 km + 16 km = 36 km

So, the two riders ended up 36 km apart from each other.

This calculation is based on the given information and the principles of distance and relative motion.
