Question

Спортсмен проехал 4 часа на машине и 5 часов на лошади.какова была скорость лошади если скорость машины на 9км/ч,чем скорость лошади,а весь путь 243 км решать с ПУСТЬ ХСРОЧНООООО​

Answer 1

Пусть х=скорость лошади, то х+9=скорость машины
По условию задачи: t машины • скорость машины = t лошади • скорость лошади
Составляем уравнение: 4(х+9)=5х
4х+36=5х
36=5х-4х
36=х
Ответ: скорость лошади=36 км/ч
Скорость машины=36+9=45 км/ч

Answer 2

Calculating the Horse's Speed

To calculate the speed of the horse, we can use the formula: speed = distance / time

Given: - The sportsman traveled 4 hours by car at a speed of 9 km/h. - He also traveled 5 hours on horseback. - The total distance traveled was 243 km.

First, let's calculate the distance traveled by the car: distance_car = speed_car * time_car

Using the given speed of the car (9 km/h) and the time traveled (4 hours): distance_car = 9 km/h * 4 h = 36 km

Now, we can calculate the distance traveled by the horse: distance_horse = total_distance - distance_car distance_horse = 243 km - 36 km = 207 km

Now, we can calculate the speed of the horse using the time traveled on horseback: speed_horse = distance_horse / time_horse

Given that the time traveled on horseback was 5 hours: speed_horse = 207 km / 5 h = 41.4 km/h

So, the speed of the horse was 41.4 km/h.

Final Answer

The speed of the horse was 41.4 km/h.
