Question

Решить задачу ехала со скоростью 16 км час и проехал расстояние от города до дачного посёлка за 03:00 обратно он тоже расстояние проехал за 04:00 с какой скоростью ехал велосипедист в город

Answer 1

Дано
V1=16км/ч
V2-?
t1-3Часа
t2-4Часа
S-?
Найти V-?
S=V*t     S=16*3=48км-Расстояние от города до села
V2=48/4=12км/ч
Ответ 12км/ч

Answer 2

Найдём расстояние= скорость *время
16*3=48 км-расстояние
Обратная скорость= расстояние/время
48:4=12 км/ч

Answer 3

Problem Analysis

To solve this problem, we need to find the speed at which the cyclist traveled from the city to the dacha settlement. We are given that the cyclist traveled the distance from the city to the dacha settlement in 3 hours and returned in 4 hours. Let's denote the speed of the cyclist as x km/h.

Solution

To find the speed of the cyclist, we can use the formula: speed = distance / time.

Let's assume the distance from the city to the dacha settlement is d km.

From the given information, we can write two equations:

1. From the city to the dacha settlement: - Speed = 16 km/h - Time = 3 hours - Distance = d km

2. From the dacha settlement back to the city: - Speed = x km/h - Time = 4 hours - Distance = d km

Using the formula speed = distance / time, we can write the following equations:

1. From the city to the dacha settlement: - 16 km/h = d km / 3 hours

2. From the dacha settlement back to the city: - x km/h = d km / 4 hours

To find the value of x, we can solve these two equations simultaneously.

Solving the Equations

Let's solve the equations to find the value of x.

From the first equation, we can isolate d: - 16 km/h = d km / 3 hours - Multiplying both sides by 3 hours: 16 km/h * 3 hours = d km - Simplifying: 48 km = d km

Now, we can substitute this value of d into the second equation: - x km/h = 48 km / 4 hours - Simplifying: x km/h = 12 km/h

Answer

The cyclist traveled from the city to the dacha settlement at a speed of 12 km/h.
