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
A man takes twice as long to row a distance against the stream as to row the same distance in favour of the stream. The ratio of the speed of the boat (in still water) and the stream is:Speed of a boat in standing water is 9 kmph and the speed of the stream is 5 kmph. A man rows to a place at a distance of 105 km and comes back to the starting point. The total time taken by him is:two trains are moving in opposite directions at 60 km/hr and 90 km/hr. Their lengths are 1/10 km and 9 km respectively. The time taken by slower train to cross the faster train in seconds is -A man can row three-quarters of a kilometre against the stream in 11×(1/4) minutes and down the stream in 7×(1/2) minutes. The speed (in km/hr) of the man in still water is:In a 300 m race A beats B by 5 metre or 6 seconds. B's time over the course is -A boatman goes 2 km against the current of the stream in 1 hour and goes 1 km along the current in 10 minutes. How long will it take to go 5 km in stationary water?A boat covers a certain distance downstream in 1 hour, while it comes back in 1x(1/2) hours.
