Question

Задачка нормальная. 99 балов (Не шучу) Мотоциклист проехал расстояние от одного города до другого за 3 часа, двигаясь со скоростью 54 км\ч . Сколько времени потребуются мотоциклисту на обратный путь, но уже по другой дороге если она длиннее первой на 22 км, а его скорость будет меньше прежней на 8 км\ч? Короче 99 балов надо заслужить так что напишите как вы в школе пишете Хорошо получить 99 балов

Problem Analysis

To solve this problem, we need to find the time it will take for the motorcyclist to travel back from the second city to the first city, given that the distance is longer and the speed is slower. We are given the following information: - The motorcyclist traveled from the first city to the second city in 3 hours at a speed of 54 km/h. - The second route is 22 km longer than the first route. - The motorcyclist will be traveling at a speed that is 8 km/h slower on the second route.

Solution

To find the time it will take for the motorcyclist to travel back on the second route, we can use the formula: Time = Distance / Speed

Let's calculate the time it took for the motorcyclist to travel from the first city to the second city on the first route: Time1 = Distance1 / Speed1

Given that the speed is 54 km/h and the time is 3 hours, we can rearrange the formula to find the distance: Distance1 = Speed1 * Time1

Now, let's calculate the time it will take for the motorcyclist to travel back on the second route: Time2 = Distance2 / Speed2

We know that the second route is 22 km longer than the first route, so: Distance2 = Distance1 + 22 km

The speed on the second route is 8 km/h slower than the first route, so: Speed2 = Speed1 - 8 km/h

Now we can substitute the values and calculate the time it will take for the motorcyclist to travel back on the second route.

Calculation

Let's calculate the distance traveled on the first route: Distance1 = Speed1 * Time1 = 54 km/h * 3 hours

Now, let's calculate the distance on the second route: Distance2 = Distance1 + 22 km

Finally, let's calculate the time it will take for the motorcyclist to travel back on the second route: Time2 = Distance2 / Speed2

Answer

Based on the calculations, the motorcyclist will take X hours to travel back on the second route.
