Question

Когда Николай прошёл 2/5 длины дорожки ему осталось пройти 30 метров Какова длина дорожки

Answer 1

Ему осталось пройти 30 м или 3/5 всей дорожки
то есть вся дорожка 30+20=50 метров

Answer 2

30 м = 3/5
30:3*5=50 м

Answer 3

Calculation of the Length of the Track

To find the length of the track, we can use the information provided in the question. According to the question, when Nikolai has completed 2/5 of the track, he still has 30 meters left to go. We need to determine the total length of the track.

Let's assume the length of the track is represented by the variable "x".

Based on the given information, we can set up the following equation:

2/5 * x + 30 = x

To solve for "x", we can simplify the equation:

2/5 * x + 30 = x 2/5 * x - x = -30 (2/5 - 1) * x = -30 -3/5 * x = -30

Now, we can solve for "x" by multiplying both sides of the equation by -5/3:

(-3/5 * x) * (-5/3) = -30 * (-5/3) x = 50

Therefore, the length of the track is 50 meters.
