Answer 3

Problem Analysis

We have two cars traveling towards each other on the same road. The distance between the two cities is 440 km. The first car is traveling at a speed of 60 km/h, and the second car is traveling at a speed of 50 km/h. 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 since they are traveling towards each other.

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

Calculation

The relative speed of the two cars is the sum of their speeds: 60 km/h + 50 km/h = 110 km/h.

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

Time = Distance / Relative Speed

Time = 440 km / 110 km/h

Time = 4 hours

Therefore, the cars will meet after 4 hours.

Answer

The two cars will meet after 4 hours of driving.
