Question

Відстань між двома містами 112 км.Із них виїхало одночастно назустріч один одному двоє велосипедистів.Один із них проїхав за годину 16 км,а другий - 12 км.Через скільки годин вони зустрінуться?

Answer 1

S = v * t - формула пути

1) 16 + 12 = 28 (км/ч) - скорость сближения

2) 112 : 28 = 4 (ч) - через 4 часа велосипедисты встретятся.

Ответ: вони зустрiнуться через 4 годины.

Answer 2

Problem Analysis

We have two cyclists who start from opposite ends of a 112 km distance and are cycling towards each other. One cyclist travels at a speed of 16 km/h, while the other cyclist travels at a speed of 12 km/h. We need to determine how many hours it will take for them to meet.

Solution

To solve this problem, we can use the formula:

Time = Distance / Speed

Let's calculate the time it takes for each cyclist to cover their respective distances.

For the first cyclist: Distance = 16 km Speed = 16 km/h Time = Distance / Speed = 16 km / 16 km/h = 1 hour

For the second cyclist: Distance = 12 km Speed = 12 km/h Time = Distance / Speed = 12 km / 12 km/h = 1 hour

Since both cyclists take 1 hour to cover their respective distances, they will meet after 1 hour.

Answer

The two cyclists will meet after 1 hour.

Explanation

When two cyclists start from opposite ends of a 112 km distance and cycle towards each other, they will meet at the midpoint of the distance. In this case, since the distance is 112 km, they will meet at the 56 km mark. Since one cyclist travels at a speed of 16 km/h and the other at 12 km/h, they will both cover their respective distances in 1 hour and meet at the 56 km mark.
