Question

Путешественники хотели пройти за 4 дня 50 км. в первый день они прошли 16 км. во второй день на 5 км. меньше чем в третий день. сколько путешествинникам останется пройти за 4 день?

Answer 1

Пусть в третий день путешественники прошли х км, тогда во второй день они прошли х - 5 км . Составим уравнение: 
16 + х + (х - 5) + (50 - 16 + х + (х - 5) ) = 50
16 + х + х - 5 + 50 - 16 + х + х - 5 = 50
40 + 4х = 50 
4х = 50 - 40
4х = 10
х = 2,5

Ответ: 2,5 км .

Answer 2

Calculation of Remaining Distance

To calculate the remaining distance the travelers have to cover on the fourth day, we need to gather the information provided:

- On the first day, they covered 16 km. - On the second day, they covered 5 km less than on the third day.

Let's break down the information step by step:

1. On the second day, they covered 5 km less than on the third day. This means that the distance covered on the second day is equal to the distance covered on the third day minus 5 km.

- Distance covered on the second day = Distance covered on the third day - 5 km

2. We know that the total distance they need to cover in 4 days is 50 km. So, we can calculate the remaining distance they have to cover on the fourth day.

- Remaining distance on the fourth day = Total distance - Distance covered on the first day - Distance covered on the second day - Distance covered on the third day

Let's calculate the remaining distance step by step:

1. Distance covered on the second day = Distance covered on the third day - 5 km

2. Remaining distance on the fourth day = 50 km - Distance covered on the first day - Distance covered on the second day - Distance covered on the third day

Now, let's substitute the values and calculate the remaining distance.

1. Distance covered on the second day = Distance covered on the third day - 5 km

- Distance covered on the second day = (Distance covered on the third day) - 5 km 2. Remaining distance on the fourth day = 50 km - Distance covered on the first day - Distance covered on the second day - Distance covered on the third day

- Remaining distance on the fourth day = 50 km - 16 km - (Distance covered on the third day) - (Distance covered on the third day - 5 km)

Unfortunately, we don't have the exact value for the distance covered on the third day. Without that information, we cannot calculate the remaining distance on the fourth day. Could you please provide the distance covered on the third day?
