Question

За 3h всадник проехал 36 км, а автомобиль [Спарк] за 2h проехал 120 км 1) на сколько скорость [Спарка] больше скорости всадника?2) Во сколько раз скорость [Спарка] больше скорости всадника?​

Answer 1

Ответ:

Объяснение:

1) 36 : 3 =12 (км/ч) - скорость всадника

2) 120 : 2 = 60 (км/ч) - скорость автомобиля

3) 60 - 12 = 48 (км) - на столько км скорость автомобиля больше скорости всадника

4) 60 : 12 = 5 (р) - во столько раз скорость автомобиля больше скорости всадника

Ответ: на 48км, в 5 раз

Answer 2

Calculation of Speed

To answer the given questions, we need to calculate the speeds of both the horse rider and the car.

Given information: - The horse rider traveled 36 km in 3 hours. - The car (Spark) traveled 120 km in 2 hours.

To calculate the speed, we use the formula: speed = distance / time.

1) Speed of the horse rider: - Distance = 36 km - Time = 3 hours - Speed = 36 km / 3 hours = 12 km/h.

2) Speed of the car (Spark): - Distance = 120 km - Time = 2 hours - Speed = 120 km / 2 hours = 60 km/h.

Comparison of Speeds

Now, let's compare the speeds of the car and the horse rider.

1) The speed of the car (Spark) is 60 km/h. 2) The speed of the horse rider is 12 km/h.

To answer the given questions:

1) The speed of the car (Spark) is 48 km/h faster than the speed of the horse rider. (60 km/h - 12 km/h = 48 km/h). 2) The speed of the car (Spark) is 5 times faster than the speed of the horse rider. (60 km/h / 12 km/h = 5).

Therefore, the car (Spark) is 48 km/h faster and 5 times faster than the horse rider.
