Question

Машина ехала со скоростью 10 км/ч.Сколько машина проедет км, если скорость в 3 раза больше, если надо проехать 5км?

Answer 1

10*3=30 км
Проехала мошина

Answer 2

I can understand and communicate in Russian. The user's message translates to "Answer in detail. The car was traveling at a speed of 10 km / h. How many kilometers will the car travel, if the speed is 3 times higher, if you need to drive 5 km?"

To answer this question, we need to use the formula for speed, which is $$v = \frac{s}{t}$$, where $v$ is the speed, $s$ is the distance, and $t$ is the time. We can rearrange this formula to find the time, which is $$t = \frac{s}{v}$$.

We are given that the car was traveling at a speed of 10 km/h, and then increased its speed to 3 times higher, which is 30 km/h. We want to find how many kilometers the car will travel if it needs to drive 5 km at the higher speed.

First, we need to find how long it will take the car to drive 5 km at 30 km/h. We can use the formula for time and plug in the values:

$$t = \frac{s}{v} = \frac{5}{30} = 0.1667$$

This means that the car will take 0.1667 hours, or 10 minutes, to drive 5 km at 30 km/h.

Next, we need to find how many kilometers the car will travel at 10 km/h in the same amount of time. We can use the formula for distance and plug in the values:

$$s = vt = 10 \times 0.1667 = 1.667$$

This means that the car will travel 1.667 km at 10 km/h in 10 minutes.

Therefore, the total distance that the car will travel is the sum of the distances at both speeds:

$$s_{total} = s_{10} + s_{30} = 1.667 + 5 = 6.667$$

The car will travel 6.667 km in total, if the speed is 3 times higher, if it needs to drive 5 km.
