Answer 2

Problem Analysis

We have two trains traveling towards each other from two cities. The distance between the cities is 492 km. The first train is traveling at a speed of 60 km/h, and the second train is traveling at a speed of 63 km/h. We need to find out how long it will take for the trains to meet and how far each train will travel.

Calculation

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

Time = Distance / Relative Speed

The relative speed of the two trains is the sum of their individual speeds. So, the relative speed is 60 km/h + 63 km/h = 123 km/h.

Substituting the values into the formula, we get:

Time = 492 km / 123 km/h

Simplifying the equation, we find:

Time = 4 hours

Therefore, the trains will meet after 4 hours.

To find the distance traveled by each train, we can multiply the speed of each train by the time it takes to meet.

For the first train: Distance = Speed * Time = 60 km/h * 4 hours = 240 km

For the second train: Distance = Speed * Time = 63 km/h * 4 hours = 252 km

Therefore, the first train will travel 240 km, and the second train will travel 252 km.

Answer

The two trains will meet after 4 hours. The first train will travel 240 km, and the second train will travel 252 km.
