QUESTION: একটি train ঢাকা থেকে চট্টগ্রামের দিকে 62 km per hour গতিতে রওনা দিল এবং একই সময়ে অন্য একটি train চট্টগ্রাম থেকে ঢাকার দিকে 48 km per hour গতিতে একই রুটে রওনা দিল। তারা মিলিত হওয়ার এক ঘণ্টা আগে দুটি train-এর মধ্যে দূরত্ব কত ছিল? সমাধান: *প্রদত্ত তথ্য বিশ্লেষণ: -ঢাকা থেকে চট্টগ্রামগামী train-এর গতি: 62 km/h -চট্টগ্রাম থেকে ঢাকাগামী train-এর গতি: 48 km/h -উভয় train একই রুটে চলছে *train দুটির আপেক্ষিক গতি নির্ণয়: -62 + 48 = 110 km/h -মিলিত হওয়ার এক ঘণ্টা আগে তারা যে দূরত্ব অতিক্রম করবে: 110 km সুতরাং, মিলিত হওয়ার এক ঘণ্টা আগে train দুটির মধ্যে দূরত্ব ছিল 110 km।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.
