Question

Мотогонщик преодолел первый участок трассы за 54 с второй за 46 секунд а третий - на n секунд быстрее чем второй сколько времени затратил мотогонщик на прохождение этих трёх участков? найдите значение полученного выражения если n=9;17;22ПОМОГИТЕ ПОЖАЛУЙСТА ОЧЕНЬ НАДО ДАМ 105 БАЛЛОВ

Answer 1

54+46+ (46-n)=146-n
146-9=137
146-17=129
146-22=124

Answer 2

1уч-54с
2уч.-46с
3уч.-(n+46)с
Что бы узнать сколько мотогонщик затратил времени на прохождения трёх участков, составим выражение:
54+46+(n+46)=( упростим)=100+n+46=n+146
n+46(с)-затратил мотогонщик на прохождения трёх участков.
n=9,n+146=9+146=155
n=17,n+146=17+146=163
n=22,n+146=22+146=168

Answer 3

Calculating the Time Taken for Each Segment

To calculate the time taken for each segment, we can use the given information about the time taken for the first, second, and third segments of the track.

Let's denote the time taken for the first segment as t1, the time taken for the second segment as t2, and the time taken for the third segment as t3.

Given: - Time taken for the first segment (t1) = 54 seconds - Time taken for the second segment (t2) = 46 seconds - Time taken for the third segment (t3) = n seconds, where n can be 9, 17, or 22

Calculating the Total Time Taken

The total time taken to complete all three segments can be calculated by adding the time taken for each segment.

The total time taken (T) is given by: T = t1 + t2 + t3

Let's calculate the total time taken for each value of n (9, 17, and 22) to find the corresponding values.

1. For n = 9: - t1 = 54 seconds - t2 = 46 seconds - t3 = 9 seconds - T = 54 + 46 + 9 = 109 seconds

2. For n = 17: - t1 = 54 seconds - t2 = 46 seconds - t3 = 17 seconds - T = 54 + 46 + 17 = 117 seconds

3. For n = 22: - t1 = 54 seconds - t2 = 46 seconds - t3 = 22 seconds - T = 54 + 46 + 22 = 122 seconds

Conclusion

The total time taken by the motorcyclist to complete the three segments of the track is as follows: - For n = 9, the total time taken is 109 seconds. - For n = 17, the total time taken is 117 seconds. - For n = 22, the total time taken is 122 seconds.

Therefore, the values of the total time taken for the given values of n (9, 17, and 22) are 109 seconds, 117 seconds, and 122 seconds, respectively.
