Question

За три дня туристы прошли 87,69 км. За первые два дня они прошли 60,98. Сколько километров прошли туристы каждый день, если во второй день они прошли на 5,42 км больше, чем в третий?

Answer 1

1)60,98-22,12=38,86(1 день)

2)5,42+16,7=22,12(2 день)

3)87,68-60,98=16,7(3 день)

ответ:

1 день: 38,86 км

2 день: 22,12 км

3 день: 16, 7 км

Answer 2

Calculating the Distance Covered by Tourists Each Day

To calculate the distance covered by the tourists each day, we can use the given information and solve for the distance covered on each day.

Let's denote: - Distance covered on the first day as D1 - Distance covered on the second day as D2 - Total distance covered in three days as Total

We are given the following information: - Total distance covered in three days = 87.69 km - Distance covered in the first two days = 60.98 km - Distance covered on the second day is 5.42 km more than the distance covered on the third day

Using this information, we can set up the following equations:

1. D1 + D2 + D3 = Total 2. D1 + D2 = 60.98 3. D2 = D3 + 5.42

Let's solve for the distances covered on each day.

Solution:

From the given information, we have: - Total distance covered in three days = 87.69 km- Distance covered in the first two days = 60.98 km- Distance covered on the second day is 5.42 km more than the distance covered on the third day

Using the equations above, we can solve for the distances covered on each day.

We can start by substituting the value of D2 from equation 2 into equation 1: D1 + (D3 + 5.42) = 87.69

Now, we can substitute the value of D1 + D2 from equation 2 into the above equation: (60.98) + (D3 + 5.42) = 87.69

Solving for D3: D3 = 87.69 - 60.98 - 5.42

D3 = 21.29 km

Now that we have the value of D3, we can find D2: D2 = D3 + 5.42 D2 = 21.29 + 5.42 D2 = 26.71 km

Finally, we can find D1: D1 = 60.98 - D2 D1 = 60.98 - 26.71 D1 = 34.27 km

Conclusion:

Therefore, the tourists covered the following distances each day: - First day: 34.27 km - Second day: 26.71 km - Third day: 21.29 km
