Question
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?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
