Question

Два грузовика едут по шоссе со скоростью 60 км/ч,расстояние между ними-360 м. Когда грузовик сворачивает на проселочную дорогу, его скорость снижается до 20 км/ч.Сколько метров будет между грузовиками на просёлочной дороге?

Answer 1

1)60/20=3   2)360/3=120 метров

Answer 2

Calculation of the Distance Between the Trucks on the Country Road

To calculate the distance between the trucks on the country road, we need to consider the initial distance between the trucks on the highway and the reduction in speed when one of the trucks turns onto the country road.

Given: - Speed of the trucks on the highway: 60 km/h - Initial distance between the trucks on the highway: 360 m - Speed of the truck on the country road: 20 km/h

To find the distance between the trucks on the country road, we can use the formula:

Distance = Speed x Time

Let's calculate the time it takes for the truck to reach the country road:

Time = Distance / Speed

The time it takes for the truck to reach the country road is:

Time = 360 m / 60 km/h = 6 seconds

Now, let's calculate the distance between the trucks on the country road:

Distance = Speed x Time = 20 km/h x 6 seconds

To convert the speed from km/h to m/s, we need to multiply it by 1000/3600:

Distance = (20 km/h x 1000/3600) m/s x 6 seconds

Simplifying the equation:

Distance = (20 x 1000 x 6) / (3600) meters

Calculating the value:

Distance = 200 meters

Therefore, the distance between the trucks on the country road will be 200 meters.
