Question

Мотоциклист со скоростью m догоняет велосипедиста со скоростью n между ними щас b километров,через сколько времени догонит?

Answer 1

1) ( M - N ) км/час - скорость сближения 
2) B / ( M - N ) час - время, когда мотоциклист догонит велосипедиста 

Answer 2

Problem Analysis

We are given that a motorcyclist is chasing a cyclist. The motorcyclist has a speed of m km/h, while the cyclist has a speed of n km/h. The initial distance between them is b km. We need to determine how long it will take for the motorcyclist to catch up to the cyclist.

Solution

To solve this problem, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the difference between the speeds of the motorcyclist and the cyclist.

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

Calculation

The relative speed is given by (m - n) km/h.

The distance between the motorcyclist and the cyclist is b km.

Using the formula, the time it will take for the motorcyclist to catch up to the cyclist is:

Time = b / (m - n) hours

Therefore, the motorcyclist will catch up to the cyclist in b / (m - n) hours.

Answer

The motorcyclist will catch up to the cyclist in b / (m - n) hours.

Please note that the above calculation assumes constant speeds for both the motorcyclist and the cyclist. If the speeds change during the chase, the calculation may not be accurate.
