Answer 1

72 метра в час это 0.072 км в час.Нужно 600 : (0.072+80)

Answer 2

Problem Analysis

We have two cars traveling towards each other from two different cities. The distance between the cities is 600 kilometers. The first car is traveling at a speed of 72 kilometers per hour, and the second car is traveling at a speed of 80 kilometers per hour. We need to determine how many hours it will take for the cars to meet.

Solution

To find the time it takes for the cars to meet, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the sum of the speeds of the two cars.

Let's calculate the time it takes for the cars to meet.

Calculation

The distance between the two cities is 600 kilometers. The speed of the first car is 72 kilometers per hour. The speed of the second car is 80 kilometers per hour.

The relative speed of the two cars is 72 + 80 = 152 kilometers per hour.

Using the formula, we can calculate the time it takes for the cars to meet:

Time = Distance / Relative Speed

Time = 600 kilometers / 152 kilometers per hour

Time ≈ 3.947 hours

Therefore, it will take approximately 3.947 hours for the cars to meet.

Answer

The cars will meet approximately 3.947 hours after they start traveling towards each other.
