Question

Из села в город выехал мотоциклист со скоростью 42 км/ч. спустя 2 ч навстречу ему выехал велосипед со скоростью 22 км/ч. сколько времени был в пути велосипед до встречи с мотоциклистом, если расстояние от села до города составляет 340 км?

Answer 1

Шутка! На велосипеде и 340 км - ДОЛГО.
ДАНО
V1 = 42 км/час - скорость мото
t1 = 2 час - время до велостарта 
V2 = 22 км/час - скорость вело
S=340 км - путь
НАЙТИ
t2=? - время вело.
РЕШЕНИЕ
1) Путь мото до старта вело?
s1 = V1*t1 = 42*2=84 км
2) Расстояние  до встречи?
s2 = S-s1 = 340-84 = 256 км
3) Время до встречи при движении на встречу?
t2 = s2/(V1+V2) = 256/(42+22) = 4 часа
ОТВЕТ: Встретятся через 4 часа.

Answer 2

Calculation of the Time Taken by the Bicycle to Meet the Motorcyclist

To calculate the time taken by the bicycle to meet the motorcyclist, we can use the formula:

Time = Distance / Speed

Given that the motorcyclist is traveling at a speed of 42 km/h and the bicycle is traveling at a speed of 22 km/h, we need to determine the time it takes for the bicycle to cover the distance between the village and the city, which is 340 km.

Using the formula, we can calculate the time taken by the bicycle as follows:

Time taken by the bicycle = Distance / Speed = 340 km / 22 km/h

Let's calculate the time taken by the bicycle to meet the motorcyclist.

340 km / 22 km/h = 15.45 hours

Therefore, the bicycle takes approximately 15.45 hours to meet the motorcyclist.

Please note that the calculated time is an approximation and may not account for factors such as breaks or changes in speed during the journey.
