দেওয়া আছে, ট্র্যাকের দৈর্ঘ্য = 12 কিমি ফরজানার গতি = 10 কিমি/ঘণ্টা নূপুরের গতি = 8 কিমি/ঘণ্টা তারা বিপরীত দিক থেকে শুরু করেছে যেহেতু তারা একে অপরের দিকে আসছে, তাই আপেক্ষিক গতি = 10 + 8 = 18 কিমি/ঘণ্টা সময় = দূরত্ব ÷ আপেক্ষিক গতি সময় = 12 ÷ 18 = 2/3 ঘণ্টা ফরজানার অতিক্রান্ত দূরত্ব = গতি × সময় = 10 × (2/3) = 20/3 কিমি = 20/3 × 1000 = 6666.67 মিটার ≈ 6667 মিটারRelated 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-
