Answer 1

Решение:
3*5=15(км)- прошел за 3 часа
39-15=24 (км)- осталось
24 : 6 = 4 (км/ч)- прошел отряд остальную часть пути
Ответ:4 км/ч.

Answer 2

5*3=15
39-15=24
24:6=4

Answer 3

Problem Analysis

We are given that a squad traveled a total distance of 39 km. The squad traveled at a speed of 5 km/h for the first 3 hours and then completed the remaining distance in 6 hours. We need to find the speed at which the squad traveled the remaining distance.

Solution

To find the speed at which the squad traveled the remaining distance, we can use the formula:

Speed = Distance / Time

Let's calculate the distance traveled in the first 3 hours: Distance1 = Speed1 * Time1 = 5 km/h * 3 h = 15 km

Now, we can calculate the remaining distance: Distance2 = Total Distance - Distance1 = 39 km - 15 km = 24 km

We know that the squad took 6 hours to cover the remaining distance. Therefore, we can calculate the speed at which the squad traveled the remaining distance: Speed2 = Distance2 / Time2 = 24 km / 6 h = 4 km/h

Answer

The squad traveled the remaining distance at a speed of 4 km/h.

Explanation

The squad traveled a total distance of 39 km. In the first 3 hours, they traveled at a speed of 5 km/h, covering a distance of 15 km. The remaining distance of 24 km was covered in 6 hours, resulting in a speed of 4 km/h.
