Question

Помогите плиз Задачу выражение Первые 2ч турист шёл со скоростью 5 км/ч,затем ещё 3 ч со скростью 6 км/ч .Потом он обнаружил, что потерял шапку, и плбежад нвзад со скоростью 11км/ч . Шапку турист нашёл , пробежал целый час. На каком расстоянии от начальной точки турист потерял шапку????? Составь выражение для вычисления

Answer 1

5 * 2 + 6 * 3 - 11 * 1 = 10 + 18 - 11 = 17(км)
Ответ: на расстоянии 17км от начальной точки турист потерял шапку.

Answer 2

(2x5+3x6)-11=17
Ответ:17 километров.

Answer 3

Problem Analysis

To solve this problem, we need to find the distance from the initial point where the tourist lost his hat. We can break down the problem into three parts: 1. The distance covered in the first 2 hours at a speed of 5 km/h. 2. The distance covered in the next 3 hours at a speed of 6 km/h. 3. The distance covered in 1 hour while searching for the hat at a speed of 11 km/h.

Solution

Let's calculate the distance covered in each part and then add them up to find the total distance.

1. Distance covered in the first 2 hours at a speed of 5 km/h: - Time = 2 hours - Speed = 5 km/h - Distance = Speed x Time = 5 km/h x 2 hours = 10 km

2. Distance covered in the next 3 hours at a speed of 6 km/h: - Time = 3 hours - Speed = 6 km/h - Distance = Speed x Time = 6 km/h x 3 hours = 18 km

3. Distance covered in 1 hour while searching for the hat at a speed of 11 km/h: - Time = 1 hour - Speed = 11 km/h - Distance = Speed x Time = 11 km/h x 1 hour = 11 km

Now, let's add up the distances covered in each part to find the total distance:

Total distance = Distance in part 1 + Distance in part 2 + Distance in part 3 = 10 km + 18 km + 11 km = 39 km

Therefore, the tourist lost his hat at a distance of 39 km from the initial point.

Mathematical Expression

The mathematical expression to calculate the distance from the initial point where the tourist lost his hat is:

Distance = (2 hours x 5 km/h) + (3 hours x 6 km/h) + (1 hour x 11 km/h)

Simplifying the expression:

Distance = 10 km + 18 km + 11 km = 39 km

So, the mathematical expression to calculate the distance is:

Distance = 10 + 18 + 11 = 39 km
