Question

Один велосипедист ехал 5 часов со скоростью 12км/ч. Второй это же расстояние проехал за 3 часа. С какой скоростью ехал второй велосипедист?

Answer 1

Ответ:

Пошаговое объяснение:

t=5 ч

V1=12 км/ч

t2=3 ч

V2=?км/ч

1) 5*12=60 (км) расстояние, которое  проехал 1 велосипедист

2) 60/3=20 (км/ч) скорость второго велосипедиста.

Answer 2

Ответ:

12*5=60км - Общий путь

60:3=20км/ч - Скорость 2-ого велосипедиста

Ответ: 20 км/ч

Answer 3

Problem Analysis

We are given that the first cyclist traveled for 5 hours at a speed of 12 km/h, and the second cyclist traveled the same distance in 3 hours. We need to find the speed at which the second cyclist was traveling.

Solution

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

Speed = Distance / Time

Let's calculate the distance traveled by the first cyclist using the formula:

Distance = Speed * Time

For the first cyclist: - Speed = 12 km/h - Time = 5 hours

Substituting the values into the formula, we get:

Distance = 12 km/h * 5 hours = 60 km

Now, let's calculate the speed of the second cyclist using the formula:

Speed = Distance / Time

For the second cyclist: - Distance = 60 km (same as the first cyclist) - Time = 3 hours

Substituting the values into the formula, we get:

Speed = 60 km / 3 hours = 20 km/h

Therefore, the second cyclist was traveling at a speed of 20 km/h.

Answer

The second cyclist was traveling at a speed of 20 km/h.
