Question

Из двух посёлков в 9 ч утра навстречу друг другу отправились два лыжника один из них шёл до встречи 4 ч со скоростью 18 км/ч другой прошёл на 8 км меньше на каком расстоянии друг от друга находятся посёлки на каком рсстоянии друг от друга они оказались через 2 часа

Answer 1

4×18=72 км до встречи прошёл первый лыжник
72-8=64 км прошёл второй лыжник
72+64=136 км расстояние между поселками
72÷2+64÷2=68 км расстояние между лыжниками через 2 часа.

Answer 2

1)4*18=52(км)-прошол 1 
2)52-8=44(км)-прошол 2
3)44+52=96(км)
4)18*2=36(км)

Answer 3

Problem Analysis

Two skiers set off towards each other from two villages at 9:00 AM. One skier walks for 4 hours at a speed of 18 km/h until they meet, while the other skier walks 8 km less. We need to find the distance between the villages and the distance between the skiers after 2 hours.

Distance between the Villages

To find the distance between the villages, we need to calculate the total distance covered by both skiers until they meet. Since one skier walks for 4 hours at a speed of 18 km/h, the distance covered by that skier is 4 hours multiplied by 18 km/h, which is 72 km.

Now, we know that the other skier walks 8 km less than the first skier. Therefore, the distance covered by the second skier is 72 km minus 8 km, which is 64 km.

To find the total distance between the villages, we add the distances covered by both skiers: 72 km plus 64 km, which equals 136 km.

Distance between the Skiers after 2 Hours

To find the distance between the skiers after 2 hours, we need to calculate the distance covered by each skier individually.

The first skier walks for 4 hours, so after 2 hours, they would have covered half the distance. Therefore, the distance covered by the first skier after 2 hours is 72 km divided by 2, which is 36 km.

The second skier walks 8 km less than the first skier, so after 2 hours, they would have covered 8 km less than half the distance covered by the first skier. Therefore, the distance covered by the second skier after 2 hours is 36 km minus 8 km, which is 28 km.

To find the distance between the skiers after 2 hours, we subtract the distance covered by the second skier from the distance covered by the first skier: 36 km minus 28 km, which equals 8 km.

Conclusion

The distance between the villages is 136 km, and the distance between the skiers after 2 hours is 8 km.
