Question

От пристани города Нижний новгород отошли одновременно в противоположных направлениях 2 теплохода. через 3 часа расстояние между ними было 204 км.Средняя скорость одного из теплоходов 32 км/ч. С какой средней скоростью шел другой теплоход

Answer 1

Путь к-рый прошел 1 теплоход за 3ч=3*32=96 км. значит 2-й прошел=204-96=108 км, и его скорость=108:3=36 км:ч

Answer 2

Problem Analysis

Two boats departed simultaneously from the pier of the city of Nizhny Novgorod in opposite directions. After 3 hours, the distance between them was 204 km. One of the boats had an average speed of 32 km/h. We need to find the average speed of the other boat.

Solution

Let's assume that the average speed of the other boat is x km/h.

We know that the distance traveled by both boats is the same. Therefore, we can set up the following equation:

Distance traveled by the first boat = Distance traveled by the second boat

The distance traveled by the first boat can be calculated by multiplying its average speed (32 km/h) by the time (3 hours):

32 km/h * 3 hours = 96 km

The distance traveled by the second boat can be calculated by subtracting the distance between the two boats (204 km) from the distance traveled by the first boat:

Distance traveled by the second boat = 204 km - 96 km = 108 km

Now we can set up the equation:

x km/h * 3 hours = 108 km

To find the value of x, we can divide both sides of the equation by 3:

x km/h = 108 km / 3 hours

Simplifying the equation:

x km/h = 36 km/h

Therefore, the average speed of the other boat is 36 km/h.

Answer

The other boat had an average speed of 36 km/h.
