Question

Один мотоциклист был в пути 3ч, другой 5ч, Они ехали с одинаковой скоростью. Второй проехал на 80 км больше первого. сколько километров проехал каждый

Answer 1

5-3=2 (ч) - разница времени у первого и второго мотоциклиста

80/2=40 (км/ч) - скорость каждого мотоциклиста

40*3=120 (км) - расстояние, которое проехал первый мотоциклист

40*5=200 (км) - расстояние, которое проехал второй мотоциклист

 

Ответ: 120 км, 200 км.

Answer 2

Problem Analysis

We have two motorcyclists who traveled for different durations but at the same speed. The second motorcyclist traveled 80 km more than the first. We need to determine the distance traveled by each motorcyclist.

Solution

Let's assume the speed of both motorcyclists is x km/h.

The first motorcyclist traveled for 3 hours. Therefore, the distance traveled by the first motorcyclist is 3x km.

The second motorcyclist traveled for 5 hours. Therefore, the distance traveled by the second motorcyclist is 5x km.

According to the problem, the second motorcyclist traveled 80 km more than the first motorcyclist. This can be expressed as:

5x = 3x + 80

To solve this equation, we can subtract 3x from both sides:

5x - 3x = 3x + 80 - 3x

Simplifying the equation:

2x = 80

Dividing both sides by 2:

x = 40

Now that we have the value of x, we can substitute it back into the equations to find the distances traveled by each motorcyclist.

The distance traveled by the first motorcyclist is:

3x = 3 * 40 = 120 km

The distance traveled by the second motorcyclist is:

5x = 5 * 40 = 200 km

Therefore, the first motorcyclist traveled 120 km, and the second motorcyclist traveled 200 km.

Answer

The first motorcyclist traveled 120 km, and the second motorcyclist traveled 200 km.
