Question

Из двух городов одновременно навстречу друг другу выехали 2 велосипедиста. скорость одного 15км/ч, другого 18 км/ч. велосипедисты встретились через 6 часов. Определить расстояние между городами.

Answer 1

Что бы найти расстояние нужно скорость умножить на время...15*6=90км.проехал первый велосипедист....затем 18*6=106...км проехал второй велосипедист..затем расстояния складываем..      106+90= 196 км расстояние между городами
         

Answer 2

Problem Analysis

Two cyclists start simultaneously from two different cities and meet after 6 hours. The speed of one cyclist is 15 km/h, and the speed of the other cyclist is 18 km/h. We need to determine the distance between the two cities.

Solution

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

Distance = Speed × Time

Let's calculate the distance traveled by each cyclist and then find the total distance between the two cities.

1. Calculate the distance traveled by the first cyclist: - Speed of the first cyclist = 15 km/h - Time = 6 hours - Distance = Speed × Time = 15 km/h × 6 hours = 90 km

2. Calculate the distance traveled by the second cyclist: - Speed of the second cyclist = 18 km/h - Time = 6 hours - Distance = Speed × Time = 18 km/h × 6 hours = 108 km

3. Calculate the total distance between the two cities: - Total distance = Distance traveled by the first cyclist + Distance traveled by the second cyclist - Total distance = 90 km + 108 km = 198 km

Therefore, the distance between the two cities is 198 km.
