QUESTION : Hasan 10 miles per hour বেগে দৌড়াতে পারে, আর Jack 8 miles per hour বেগে দৌড়াতে পারে। যদি তারা একই সময়ে একটি বিন্দু থেকে শুরু করে বিপরীত দিকে দৌড়ায়, তাহলে 10 minutes পরে তারা কত দূরে থাকবে (নিকটতম mile-এ)? সমাধান: -প্রথমে, 10 minutes কে ঘণ্টায় রূপান্তর করি: 10 minutes = 1/6 hour *Hasan'র দূরত্ব: 10 miles/hour × 1/6 hour = 5/3 miles *Jack'র দূরত্ব: 8 miles/hour × 1/6 hour = 4/3 miles মোট দূরত্ব: -5/3 miles + 4/3 miles = 9/3 miles = 3 miles -সুতরাং, 10 minutes পরে Hasan এবং Jack একে অপর থেকে 3 miles দূরে থাকবে। সঠিক উত্তর: (C) 3 milesRelated 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. If the speed of the stream be 3 kmph, what is the speed of the boat in still water?A man buys tk 20 shares paying 9% dividend. The man wants to have an interest of 12% on his money. The market value of each share is-
