Question

Автобус проехал 15 км со скоростью 40 км /ч .за это же время велосипедист проехал 13 км . чему равна скорость велосипедиста

Answer 1

Узнаем время за которое проехал автобус 15 км  15 / 40 = 0,375 часа
Узнаем скорость велосипедиста 13 / 0,375 = 34,66 км /час

Answer 2

Calculation of the Bicycle Speed

To find the speed of the cyclist, we can use the formula:

Speed = Distance / Time

Given that the bus traveled 15 km with a speed of 40 km/h, we can calculate the time it took for the bus to travel this distance:

Time = Distance / Speed = 15 km / 40 km/h

Now, we know that the cyclist traveled 13 km in the same amount of time. To find the speed of the cyclist, we can use the formula again:

Speed = Distance / Time = 13 km / (15 km / 40 km/h)

Let's calculate the speed of the cyclist:

Speed = 13 km / (15 km / 40 km/h)

Using the above formula, we can calculate the speed of the cyclist.
