Question

От двух пристаней расстояние между которыми 280 км одновременно вышли навстречу друг другу две моторные лодки через 4 ч лодки встретились скорость одной лодки 33 км ч найди скорость другой лодки

Answer 1

4*33=132 км прошла за 4 часа 1 лодка                                                                    280-132=148 км прошла 2 лодка                                                                               148:4=37 км/час скорость 2 лодки

Answer 2

280 : 4 = 70км/ч - общая скорость
70 - 33 = 37 км/ч - скорость 2-ой лодки
Ответ: 37 км/ч

Answer 3

Problem Analysis

We are given that two motorboats started simultaneously from two different piers and traveled towards each other. The distance between the piers is 280 km. After 4 hours, the boats met each other. We are also given the speed of one of the boats, which is 33 km/h. We need to find the speed of the other boat.

Solution

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

We can use the formula: Speed = Distance / Time to find the distance traveled by each boat.

Since both boats started simultaneously and traveled for 4 hours before meeting, the total distance traveled by both boats is equal to the distance between the piers, which is 280 km.

Let's calculate the distance traveled by each boat:

- Distance traveled by the first boat = Speed of the first boat * Time = 33 km/h * 4 h = 132 km - Distance traveled by the second boat = Speed of the second boat * Time = x km/h * 4 h = 4x km

Since the total distance traveled by both boats is equal to 280 km, we can write the equation:

132 km + 4x km = 280 km

Now, let's solve this equation to find the value of x.

132 km + 4x km = 280 km

Subtract 132 km from both sides:

4x km = 280 km - 132 km

4x km = 148 km

Divide both sides by 4:

x km = 148 km / 4

x km = 37 km/h

Answer

The speed of the other boat is 37 km/h.
