QUESTION : Mr. X তার বাড়ি থেকে 9:10 am-এ IBA-র দিকে রওনা দেন, যা তার বাড়ি থেকে 10 miles দূরে। তাকে 9:30 am-এর মধ্যে IBA পৌঁছাতে হবে। যদি তিনি অর্ধেক দূরত্ব 20 miles per hour গতিতে অতিক্রম করেন, তাহলে বাকি দূরত্বের জন্য তার গতি কত হতে হবে (miles per hour-এ)? -মোট দূরত্ব = 10 miles -মোট সময় = 20 মিনিট (9:10 am থেকে 9:30 am) -প্রথম অর্ধেক দূরত্ব = 5 miles, গতি = 20 miles per hour -প্রথম অর্ধেক দূরত্বের জন্য সময় = 5 / 20 = 0.25 ঘণ্টা = 15 মিনিট -বাকি সময় = 20 - 15 = 5 মিনিট -বাকি দূরত্ব = 5 miles -বাকি অংশের জন্য গতি = 5 miles / (5/60) hour = 60 miles per hour সুতরাং, সঠিক উত্তর হল (B) 60 miles per hour

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-
