Question

Мотоциклист и велосипедист едут навстречу друг другу. Через сколько часов они встретятся, если расстояние между ними 272 км, скорость велосипедиста 12км/ч, а скорость мотоциклиста 56 км/ч?

Answer 1

Ответ:

Через 4 часа произойдет встреча.

Пошаговое объяснение:

1) 12 + 56 = 68 км/ч - скорость сближения (т.е. за 1 час проходят 68 км и при этом сближаются)

2) 272 км : 68 км/ч = 4 ч

Answer 2

Calculation of Meeting Time for the Motorcyclist and Cyclist

To calculate the time it takes for the motorcyclist and cyclist to meet, we can use the formula:

Time = Distance / Relative Speed

Given: - Distance between them = 272 km - Speed of the cyclist = 12 km/h - Speed of the motorcyclist = 56 km/h

Let's calculate the meeting time step by step:

1. Calculate the relative speed of the motorcyclist and cyclist: - Relative Speed = Speed of the motorcyclist - Speed of the cyclist - Relative Speed = 56 km/h - 12 km/h = 44 km/h

2. Calculate the meeting time: - Time = Distance / Relative Speed - Time = 272 km / 44 km/h = 6.18 hours

Therefore, the motorcyclist and cyclist will meet after approximately 6.18 hours.
