Solution: প্রশ্নে বলা হচ্ছে যে, দুইজন ব্যক্তি একই স্থান থেকে একই সময়ে কিন্তু পরষ্পর বিপরীত অভিমুখে রওনা দিল । একজনের গতিবেগ অন্যজনের চাইতে 2 mph বেশী । 3 ঘন্টা পর তাদের মধ্যবর্তী দূরত্ব 30 মাইল হলে দ্রুতগামী ব্যক্তির গতিবেগ কত ছিল ? মনে করি, প্রথম জনের গতিবেগ x মাইল অপর Faster jogger গতিবেগ হবে (x + 2) মাইল আমরা জানি, গতিবেগ = অতিক্রান্ত দূরত্ব/সময় তাই অতিক্রান্ত দূরত্ব = গতিবেগ সময় তাই প্রশ্নানুযায়ী, 3x + 3(x+2) = 30 => 3x + 3(x+2) = 30 => 6x = 30 - 6 => 6x = 24 x = 24/6 = 4 অপর Faster jogger এর গতিবেগ = (x + 2) = 4 + 2 = 6 মাইল/ঘন্টা ।Related questions
