Question

Результаты поиска для фразы "Мотоциклист проехал путь между городами M и N со скоростью на 20% больше намеченной, а обратный путь- со скоростью на 20% меньше намеченной. Во сколько раз скорость мотоциклиста на обратном пути была меньше, чем по пути M и N?

Answer 1

намеченная скорость 100%

скорость туда 120%

скорость обратно 80%

120/80= в 1,5 раза

Answer 2

Calculation of the Motorcyclist's Speed on the Return Journey

To calculate the speed of the motorcyclist on the return journey, we need to consider that the motorcyclist traveled between cities M and N with a speed 20% higher than the planned speed, and on the return journey, the speed was 20% lower than the planned speed.

Let's assume the planned speed for the journey between cities M and N is x.

The motorcyclist traveled from city M to city N with a speed 20% higher than the planned speed, which is 1.2x.

On the return journey, the motorcyclist traveled with a speed 20% lower than the planned speed, which is 0.8x.

To find the ratio of the speed on the return journey to the speed on the forward journey, we divide the speed on the return journey by the speed on the forward journey:

0.8x / 1.2x = 0.67

Therefore, the speed of the motorcyclist on the return journey was 0.67 times (or approximately 67%) of the speed on the forward journey.

Please note that the above calculation assumes that the planned speed for the journey between cities M and N is the same for both the forward and return journeys.
