Question

Велосипедист,ехавший на велосипеде со скоростью 219,2 м/мин,решил догнаать своего друга,который шел пешком и находился на расстоянии 452,1 м.Скорость друга была в 3,2 раза меньше скорости велосипедиста.Через какое время велосипедист догонит друга?

Answer 1

Скорость велосипедиста = 219,2 м/мин
Скорость друга = 219,2 : 3,2 = 68,5 м/мин
452,1 : (219,2 - 68,5) = 452,1 : 150,7 = 3
Через 3 минуты он догонит друга

Answer 2

To find out how long it will take for the cyclist to catch up to his friend, we can use the formula:

Time = Distance / Speed

Let's calculate the time it will take for the cyclist to catch up to his friend.

Given: - Speed of the cyclist = 219.2 m/min - Distance between the cyclist and his friend = 452.1 m - Speed of the friend = 3.2 times slower than the cyclist's speed

Calculating the speed of the friend:

To find the speed of the friend, we can divide the speed of the cyclist by 3.2.

Speed of the friend = Speed of the cyclist / 3.2

Calculating the time it will take for the cyclist to catch up to his friend:

Now that we have the speed of the friend, we can calculate the time it will take for the cyclist to catch up to his friend using the formula mentioned earlier.

Time = Distance / Speed

Let's substitute the values into the formula:

Time = 452.1 m / (Speed of the cyclist / 3.2)

Now, let's calculate the time.
