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

1) 42+76=118 км/ч - скорость сближение                                                          2)118*2=236 (км) они проехали за 2 часа вместе                                            3) 400-236=164 (км) будет между ними через 2 часа                                      Ответ:164 км будет между мотоциклистами через 2 часа 

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 42 km/h and 76 km/h, respectively. We need to find the distance between the two motorcyclists after 2 hours.

Solution

To solve this problem, we can use the formula: Distance = Speed × Time.

Let's calculate the distance traveled by each motorcyclist after 2 hours: - Motorcyclist 1: Distance1 = Speed1 × Time = 42 km/h × 2 h = 84 km - Motorcyclist 2: Distance2 = Speed2 × Time = 76 km/h × 2 h = 152 km

Now, let's find the distance between the two motorcyclists after 2 hours. We can subtract the distance traveled by Motorcyclist 1 from the total distance between the villages: Distance between the motorcyclists = Total distance - Distance1

Substituting the values: Distance between the motorcyclists = 400 km - 84 km = 316 km

Therefore, the distance between the two motorcyclists after 2 hours will be **
