Question

Из двух сёл расстояние между которыми 96 км,одновременно навстречу другу выехали два велосипедиста.Скорост дного 13км.ч,а другого 11км.ч.Какое расстояние будет между ними через 3 часа?Через сколько часов они встретятся? по действиям срочно

Answer 1

Найдем скорость сближения велосипедистов 13+11=24 км/ч следовательно за 1 час они сблизятся 24*1=24 км за 2 часа 24*2=48 км найдем время, а 24*3=72 за 3 часа. 96:24=4 часа они встретятся

Answer 2

Расстояние между ними:
96-(13*3+11*3)=24 км
Встретятся через:
96:(11+13)=4 ч

Answer 3

Problem Analysis

We have two cyclists who start simultaneously from two different villages and are moving towards each other. The distance between the villages is 96 km. The first cyclist has a speed of 13 km/h, while the second cyclist has a speed of 11 km/h. We need to find the distance between them after 3 hours and the time it takes for them to meet.

Distance between the cyclists after 3 hours

To find the distance between the cyclists after 3 hours, we need to calculate the distance each cyclist has traveled in that time.

The distance traveled by the first cyclist in 3 hours can be calculated using the formula: distance = speed × time. Substituting the values, we get: distance = 13 km/h × 3 h = 39 km.

Similarly, the distance traveled by the second cyclist in 3 hours can be calculated as: distance = 11 km/h × 3 h = 33 km.

To find the distance between the cyclists after 3 hours, we subtract the distance traveled by the second cyclist from the total distance between the villages: distance between cyclists = 96 km - 33 km = 63 km.

Therefore, the distance between the cyclists after 3 hours is 63 km.

Time it takes for the cyclists to meet

To find the time it takes for the cyclists to meet, we can use the formula: time = distance / relative speed.

The relative speed of the two cyclists is the sum of their individual speeds: relative speed = 13 km/h + 11 km/h = 24 km/h.

Substituting the values, we get: time = 96 km / 24 km/h = 4 hours.

Therefore, it will take 4 hours for the two cyclists to meet.

Summary

To summarize, the distance between the two cyclists after 3 hours will be 63 km, and they will meet after 4 hours.
