Question

Реши задачу из двух посёлков рассотояние между корорыми 400км одновременно навстречу друг к другу выехали два мотоциклиста их скорости 42км/ч и76/км в час какое расстояние будет между мотоциклистами через 2 ч?

Answer 1

Имеем формулу: S=V×T, где S - расстояние, V - скорость, а T - время.
То есть нужно, скорость умножить на время и найти расстояние, которое проедут мотоциклисты.
S1=42×2=84 км - проехал первый мотоциклист
S2=76×2=152 км - проехал второй мотоциклист
Мы знает какое расстояние проехал каждый мотоциклист. Теперь нужно из всего расстояния (400 км) вычесть сумму пройденного расстояния обоих мотоциклистов. 
То есть, S-(S1+S2)
400-(84+152)=400-236=164 км

Answer 2

Problem Analysis

We have two motorcyclists who start simultaneously from two different villages and are traveling towards each other. The distance between the villages is 400 km. The speeds of the two motorcyclists are given as 42 km/h and 76 km/h. We need to find the distance between the motorcyclists after 2 hours.

Solution

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

Distance = Speed × Time

Let's calculate the distances traveled by each motorcyclist after 2 hours.

Motorcyclist 1: - Speed = 42 km/h - Time = 2 hours - Distance = 42 km/h × 2 hours = 84 km

Motorcyclist 2: - Speed = 76 km/h - Time = 2 hours - Distance = 76 km/h × 2 hours = 152 km

Now, let's find the distance between the motorcyclists by subtracting the distance traveled by one motorcyclist from the total distance between the villages.

Total distance between the villages = 400 km

Distance between the motorcyclists = Total distance between the villages - Distance traveled by one motorcyclist

Distance between the motorcyclists = 400 km - 84 km = 316 km

Therefore, the distance between the motorcyclists after 2 hours will be 316 km.

Answer

The distance between the two motorcyclists after 2 hours will be 316 km.
