QUESTION : একটি car highway-তে যাত্রা করছে। সকাল 10টায়, এটি একই দিকে যাওয়া একটি truck-কে পাস করে। Truck-টি 50 mph গতিতে highway-তে চলতে থাকে, আর car-টি 65 mph গতিতে চলে। দুপুর 2টায় car এবং truck-এর মধ্যে দূরত্ব কত? ব্যাখ্যা: -প্রথমে, আমরা দেখছি যে car এবং truck-এর মধ্যে সময়ের পার্থক্য 4 ঘণ্টা (সকাল 10টা থেকে দুপুর 2টা)। -Car-টি truck-এর চেয়ে দ্রুত যাচ্ছে। তাদের গতির পার্থক্য: 65 mph - 50 mph = 15 mph -এই 15 mph হল প্রতি ঘণ্টায় car truck-এর থেকে কত মাইল বেশি যাচ্ছে তার পরিমাণ। -4 ঘণ্টায়, এই পার্থক্য হবে: 15 mph × 4 hours = 60 miles -সুতরাং, দুপুর 2টায় car এবং truck-এর মধ্যে দূরত্ব হবে 60 miles, যা option (C)-তে দেওয়া আছে।Related questions
