Question

Из 2 пунктов расстояние между которыми 19 километров 500 метров одновременно в одном направлении отправились велосипедист и автомобиль скорость велосипедиста 12 километров час а скорость автомобиля 90 километров час через сколько времени автомобиль догонит велосипедиста

Answer 1

T=S:(V2-V1)
где  ( V2-V1) -скорость догона
t=19,5 :(90-12)=0,25(часа)

Answer 2

Problem Analysis

We are given that a cyclist and a car start simultaneously from two points that are 19 kilometers and 500 meters apart. The cyclist's speed is 12 kilometers per hour, and the car's speed is 90 kilometers per hour. We need to determine how long it will take for the car to catch up to the cyclist.

Solution

To solve this problem, we can use the formula: time = distance / speed.

Let's calculate the time it takes for the cyclist to cover the distance between the two points:

Distance = 19 kilometers + 500 meters = 19.5 kilometers

Cyclist's speed = 12 kilometers per hour

Time taken by the cyclist = Distance / Cyclist's speed

Now, let's calculate the time it takes for the car to cover the same distance:

Car's speed = 90 kilometers per hour

Time taken
