Question

Один велосепидист проехал некоторый путь за 9 с, двигаясь со скоростью 8м/с, другой- этот же путь за 12 с. Какова скорость второго велосепидиста. Помогите срочно!!!

Answer 1

Problem Analysis

We are given that one cyclist traveled a certain distance in 9 seconds at a speed of 8 m/s, while another cyclist traveled the same distance in 12 seconds. We need to find the speed of the second cyclist.

Solution

To find the speed of the second cyclist, we can use the formula:

Speed = Distance / Time

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

For the first cyclist: - Time = 9 seconds - Speed = 8 m/s

Using the formula, we can write:

8 = d / 9

For the second cyclist: - Time = 12 seconds - Speed = ? (unknown)

Using the formula, we can write:

Speed = d / 12

To find the speed of the second cyclist, we need to solve the equation:

d / 12 = 8

Let's solve this equation to find the value of d and then calculate the speed of the second cyclist.

Calculation

To solve the equation, we can multiply both sides by 12:

d = 8 * 12

Simplifying, we get:

d = 96

Now that we know the distance d is 96 meters, we can calculate the speed of the second cyclist:

Speed = d / 12 = 96 / 12 = 8 m/s

Answer

The speed of the second cyclist is 8 m/s.
