Question

Задача:расстояние между городами 140км.из этих городов одновременно навстречу друг другу выехали два мотоциклиста со скоростями 36км в час и 34 км в час, чему равна расстояние S между мотоциклистами через t часов,после выезда до встречи??? напишите ответ в виде формулы и её упрастите через сколько часов мотоциклисты встретятся???

Answer 1

1)140:(34+36)= через 2 часа они встретятся; 2)S=t*(34+36)=70t

Answer 2

Problem Analysis

We are given that two motorcyclists start simultaneously from two cities and travel towards each other. The speeds of the motorcyclists are 36 km/h and 34 km/h. We need to find the distance between the motorcyclists after t hours and determine when they will meet.

Solution

Let's denote the distance between the motorcyclists after t hours as S. We can use the formula:

S = (36t) + (34t)

Simplifying the equation, we get:

S = 70t

Therefore, the distance between the motorcyclists after t hours is equal to 70t kilometers.

To find the time it takes for the motorcyclists to meet, we can set up the equation:

S = 140

Substituting the value of S from the previous equation, we get:

70t = 140

Simplifying the equation, we find:

t = 2

Therefore, the motorcyclists will meet after 2 hours.

Answer

The distance between the motorcyclists after t hours is given by the formula S = 70t. The motorcyclists will meet after 2 hours.
