2) 308/77=4
Ответ 4часа

Answer 3

Problem Analysis

We have two cars traveling towards each other from two different towns. The distance between the towns is 560 km. One car travels 252 km and then breaks down. We need to calculate how long it will take for the other car to reach the broken-down car, given that its speed is 77 km/h.

Calculation

To find the time it will take for the second car to reach the broken-down car, we can use the formula:

Time = Distance / Speed

The distance the second car needs to cover is the remaining distance between the two towns after the first car breaks down. This can be calculated as:

Remaining Distance = Total Distance - Distance Traveled by the First Car

Substituting the values into the formula, we get:

Time = Remaining Distance / Speed

Let's calculate the remaining distance and the time it will take for the second car to reach the broken-down car.

Calculation Steps

1. Total Distance = 560 km 2. Distance Traveled by the First Car = 252 km 3. Remaining Distance = Total Distance - Distance Traveled by the First Car 4. Time = Remaining Distance / Speed

Calculation

1. Total Distance = 560 km 2. Distance Traveled by the First Car = 252 km 3. Remaining Distance = 560 km - 252 km = 308 km 4. Time = 308 km / 77 km/h = 4 hours

Therefore, it will take the second car 4 hours to reach the broken-down car.

Note: Please double-check the calculations to ensure accuracy.

Answer

The second car will reach the broken-down car in approximately 4 hours if its speed is 77 km/h.
