Question

Из двух лагерей выехали одновременно навстречу друг другу два юноши. Скорость юноши на мотороллере 25 км, скорость юноши на мотоцикле в 3 раза больше. Они встретились через 2 часа. Какого расстояние между лагерями?

Answer 1

25*3=75-мотоцикл
t=(75+25)*2=200км

Answer 2

25*3=75 км/ч скорость 2-го
75+25=100 км/ч скорость сближения
S=Vсближения*t= 100*2= 200 км

Answer 3

Problem Analysis

We have two boys traveling towards each other from two different camps. One boy is riding a scooter with a speed of 25 km/h, while the other boy is riding a motorcycle with a speed three times greater. They meet each other after 2 hours. We need to find the distance between the camps.

Solution

Let's assume the distance between the camps is D km.

The first boy's speed is 25 km/h, so in 2 hours, he covers a distance of 25 * 2 = 50 km.

The second boy's speed is three times greater, so his speed is 25 * 3 = 75 km/h. In 2 hours, he covers a distance of 75 * 2 = 150 km.

When they meet, the total distance covered by both boys is equal to the distance between the camps. Therefore, we can write the equation:

50 + 150 = D

Simplifying the equation:

200 = D

So, the distance between the camps is 200 km.

Answer

The distance between the two camps is 200 km.
