Question

Учащиеся колледжа ежегодно проводят летний велопробег. В 2006 году на отдельных участках трассы им удалось развить скорость до 30 км/ч. Определите, на сколько процентов увеличилась максимальная скорость по сравнению с 2000г, если тогда она составляла 25 км/ч

Answer 1

30 - х%
25 - 100%
25х=300
х=12%
ответ 12%

Answer 2

Calculation of the Increase in Maximum Speed

To determine the percentage increase in maximum speed compared to 2000, we need to calculate the difference between the maximum speeds in 2006 and 2000, and then express that difference as a percentage of the speed in 2000.

Given the information provided, the maximum speed in 2000 was 25 km/h, and in 2006, it reached 30 km/h.

To calculate the percentage increase, we can use the following formula:

Percentage Increase = ((New Value - Old Value) / Old Value) * 100

Plugging in the values, we get:

Percentage Increase = ((30 - 25) / 25) * 100

Calculating this expression, we find that the maximum speed increased by 20% compared to 2000.

Therefore, the maximum speed increased by 20% compared to 2000.
