Question

Мотоциклист догоняет Вилосипидиста сейчас между ними 23,4 км Скорость велосипидиста 13,5 км/ч Найдите скорость мотоциклиста, если известно, что мотоциклист догоняет в елосипидиста через 2/3 ч пожалуйста помогите!!! ПРОШУ ВАС!! ​

Answer 1

Ответ:

Пошаговое объяснение:

13,5×2/3=9км проедет велосипедист за 2/3часа

23,4+9=32,4км проедет мотоциклист за 2/3часа

32,4÷2/3=32,4×3/2=48,6км/час скорость мотоциклиста

Answer 2

To find the speed of the motorcyclist, we can use the formula:

Speed = Distance / Time

Given that the distance between the motorcyclist and the cyclist is 23.4 km and the cyclist's speed is 13.5 km/h, we need to find the time it takes for the motorcyclist to catch up to the cyclist.

Calculating the Time:

The time it takes for the motorcyclist to catch up to the cyclist can be calculated using the formula:

Time = Distance / Relative Speed

The relative speed is the difference in speed between the motorcyclist and the cyclist. In this case, the relative speed is the speed of the motorcyclist minus the speed of the cyclist.

Let's calculate the relative speed:

Relative Speed = Motorcyclist's Speed - Cyclist's Speed

Calculation:

Relative Speed = Motorcyclist's Speed - Cyclist's Speed Relative Speed = Motorcyclist's Speed - 13.5 km/h

Now, we can calculate the time it takes for the motorcyclist to catch up to the cyclist:

Time = Distance / Relative Speed Time = 23.4 km / (Motorcyclist's Speed - 13.5 km/h)

We are given that the motorcyclist catches up to the cyclist in 2/3 hours. Therefore, we can set up the following equation:

2/3 = 23.4 km / (Motorcyclist's Speed - 13.5 km/h)

Now, let's solve for the speed of the motorcyclist.

Solving for the Speed of the Motorcyclist:

To solve for the speed of the motorcyclist, we can rearrange the equation:

2/3 = 23.4 km / (Motorcyclist's Speed - 13.5 km/h)

Multiply both sides of the equation by (Motorcyclist's Speed - 13.5 km/h):

2/3 * (Motorcyclist's Speed - 13.5 km/h) = 23.4 km

Now, let's solve for the speed of the motorcyclist:

2/3 * Motorcyclist's Speed - 2/3 * 13.5 km/h = 23.4 km

2/3 * Motorcyclist's Speed = 23.4 km + 2/3 * 13.5 km/h

2/3 * Motorcyclist's Speed = 23.4 km + 9 km/h

2/3 * Motorcyclist's Speed = 32.4 km

Now, let's solve for the speed of the motorcyclist:

Motorcyclist's Speed = (32.4 km) / (2/3) Motorcyclist's Speed = 32.4 km * (3/2) Motorcyclist's Speed = 48.6 km/h

Therefore, the speed of the motorcyclist is 48.6 km/h.

Please note that this calculation assumes constant speeds for both the motorcyclist and the cyclist.
