    Two trains are traveling towards each other on parallel

    tracksTrain A is traveling at a speed of 80 km/hwhile train B is traveling at a speed of 60 km/hThey are initially 300 kilometres apartIf they start at the same timehow long will it take for them to meet?
    A 2.28 hours Correct Answer Incorrect Answer
    B 1.28 hours Correct Answer Incorrect Answer
    C 2.14 hours Correct Answer Incorrect Answer
    D 1.14 hours Correct Answer Incorrect Answer

    Solution

    ATQ, When two objects are moving towards each other, their relative speed is the sum of their individual speeds. In this case: The speed of Train A is 80 km/h. The speed of Train B is 60 km/h. So, their relative speed when moving towards each other is: Relative speed = Speed of Train A + Speed of Train B Relative speed = 80 km/h + 60 km/h Relative speed = 140 km/h Now, you want to find out how long it takes for them to meet, given that they are initially 300 kilometers apart. You can use the formula: Time = Distance / Relative Speed Time = 300 km / 140 km/h Time ≈ 2.14 hours
