Question

Помогите решить залачу:один автомобиль, двигаясь со скоростью 12 метра в секунду в течении 10 сек, прошел такой же путь, что и другой за 15 сек. какова скорость второго автомобиля если он двигался равномерно?

Answer 1

Дано
V1=12 м/с
t1=10 c
S1=S2
t2=15 c
V2-?
S=Vt
S1=V1*t1
S2=V2*t2
V1t1=V2t2
V2=V1t1/t2
V2=12*10/15   Решай

Answer 2

Problem Analysis

We are given that one car travels a certain distance in 10 seconds at a speed of 12 meters per second, while another car travels the same distance in 15 seconds. We need to find the speed of the second car assuming it traveled at a constant speed.

Solution

Let's assume the distance traveled by both cars is d.

The first car travels the distance d in 10 seconds at a speed of 12 meters per second. Therefore, we can calculate the distance d as follows:

d = speed * time = 12 m/s * 10 s = 120 meters The second car also travels the same distance d in 15 seconds. We need to find the speed of the second car. We can use the formula:

speed = distance / time

Substituting the values, we have:

speed = d / 15 s = 120 m / 15 s = 8 meters per second

Therefore, the speed of the second car is 8 meters per second.

Answer

The speed of the second car, assuming it traveled at a constant speed, is 8 meters per second.
