Question

Туристы на дорогу из одного населенного пункта в другой и на обратную дорогу затратили 9,5 ч.Туда они двигались со скоростью 5 км/ч,а назад 4,5 км/ч.Найдите расстояние между населенными пунктами.

Answer 1

время в одну сторонe =s/5

время в оббратую сторону =s/4,5

s/5+s/4.5=9,5

(4,5s+5s)/22,5=9,5

9,5s=22,5*9,5

s=22,5 км растояние между населенными пунктами

Answer 2

Calculation of Distance between Two Towns

To find the distance between two towns, we can use the formula:

Distance = Speed x Time

Given that the tourists spent a total of 9.5 hours traveling from one town to another and back, and their speed was 5 km/h while going and 4.5 km/h while returning, we can calculate the distance between the towns.

Let's calculate the distance step by step:

1. Calculate the time taken to go from one town to another: - Speed = 5 km/h - Time = 9.5 hours / 2 = 4.75 hours

2. Calculate the distance traveled while going: - Distance = Speed x Time = 5 km/h x 4.75 hours = 23.75 km

3. Calculate the time taken to return from the other town: - Speed = 4.5 km/h - Time = 9.5 hours / 2 = 4.75 hours

4. Calculate the distance traveled while returning: - Distance = Speed x Time = 4.5 km/h x 4.75 hours = 21.375 km

5. Calculate the total distance between the towns: - Total Distance = Distance while going + Distance while returning - Total Distance = 23.75 km + 21.375 km = 45.125 km

Therefore, the distance between the two towns is approximately 45.125 km.
