Answer 1

$1)$ $75*5=375$ (км)  - расстояние, которое проедет I автомобиль

$2)$ $860-375=485$ (км)  - расстояние, которое проедет II автомобиль

$3)$ $485:5=97$ (км/ч) - скорость II автомобиля

Ответ: $97$ км/ч

Answer 2

Problem Analysis

Two cars start simultaneously from point A in opposite directions. The speed of one car is given as 75 km/h. After 5 hours, the distance between the two cars is 860 km. We need to find the speed of the second car.

Solution

To find the speed of the second car, we can use the formula:

Speed = Distance / Time

Let's calculate the speed of the second car using this formula.

Calculation

Given: - Speed of the first car = 75 km/h - Time = 5 hours - Distance between the two cars = 860 km

Using the formula, we can calculate the speed of the second car as follows:

Speed of the second car = Distance / Time

Speed of the second car = 860 km / 5 hours

Speed of the second car = 172 km/h

Therefore, the speed of the second car is 172 km/h.

Answer

The speed of the second car is 172 km/h.
