Question

Велосипедист движется со скоростью 25 км/ч, а - автомобиль со скоростью 55 км/ч. С какой скоростью движется автомобиль относительно велосипедиста,если автомобиль движется навстречу велосипедисту

Answer 1

25+55=80 км/ч
Как-то так!)

Answer 2

Calculation of Relative Speed

To calculate the relative speed between the car and the cyclist, we need to consider that the car is moving towards the cyclist. The relative speed is the difference between the speeds of the car and the cyclist.

Given: - Speed of the cyclist: 25 km/h - Speed of the car: 55 km/h

To find the relative speed, we subtract the speed of the cyclist from the speed of the car:

Relative speed = Speed of the car - Speed of the cyclist

Relative speed = 55 km/h - 25 km/h

The relative speed of the car with respect to the cyclist, when the car is moving towards the cyclist, is 30 km/h.
