Question

Машина ехала по ровной дороге с постоянной скоростью. на спуске её скорость увеличилась в 2 раза.Затем на подъёме её скорость уменьшилась на 25км/ч и стала 95км/ч. с какой скоростью машина ехала по ровной дороге?Спс всем кто помогал вы лучшие:)

Answer 1

(25+95)/2=60 км/час Вот такой ответ

Answer 2

95+25=120Км ч120/2=60км ч

Answer 3

Calculation of the Car's Speed on a Flat Road

To determine the speed of the car on a flat road, we need to analyze the given information. Let's break down the problem step by step:

1. The car initially travels on a flat road at a constant speed. 2. On a downhill slope, the car's speed doubles. 3. On an uphill slope, the car's speed decreases by 25 km/h and becomes 95 km/h.

To find the car's speed on a flat road, we can use the information provided.

Let's assume the initial speed of the car on the flat road is x km/h.

On the downhill slope, the car's speed doubles, so it becomes 2x km/h.

On the uphill slope, the car's speed decreases by 25 km/h and becomes 95 km/h. Therefore, we can set up the following equation:

2x - 25 = 95

Now, let's solve this equation to find the value of x.

2x - 25 = 95

Adding 25 to both sides:

2x = 120

Dividing both sides by 2:

x = 60

Therefore, the car's speed on the flat road is 60 km/h.
