Question

Из одного поселка вышли одновременно в противоположных направлениях два пешехода. Один шел со скоростью 5км/ч,а другой 3км/ч.На каком расстоянии друг от друга они будут через 2часа?

Answer 1

Находим расстояние, пройденное каждого пешехода за 2 часа, т.к.они шли в противоположных направлениях, то полученные расстояния складываем.

S1=5*2=10км
S2=3*2=6км
S=S1+S2=10+6=16 км

Answer 2

Problem Analysis

Two pedestrians start walking simultaneously in opposite directions. One walks at a speed of 5 km/h, while the other walks at a speed of 3 km/h. We need to determine the distance between them after 2 hours.

Solution

To find the distance between the two pedestrians after 2 hours, we can use the formula:

Distance = Speed x Time

Let's calculate the distance traveled by each pedestrian and then find the total distance between them.

1. The first pedestrian walks at a speed of 5 km/h for 2 hours. Therefore, the distance traveled by the first pedestrian is:

Distance1 = Speed1 x Time = 5 km/h x 2 h = 10 km 2. The second pedestrian walks at a speed of 3 km/h for 2 hours. Therefore, the distance traveled by the second pedestrian is:

Distance2 = Speed2 x Time = 3 km/h x 2 h = 6 km 3. To find the total distance between the two pedestrians, we add the distances traveled by each pedestrian:

Total Distance = Distance1 + Distance2 = 10 km + 6 km = 16 km

Therefore, after 2 hours, the two pedestrians will be 16 kilometers apart from each other.

Answer

The two pedestrians will be 16 kilometers apart from each other after 2 hours.
