QUESTION : Sharif একটি 2 mile রেস গড়ে 8 miles per hour বেগে দৌড়েছে। যদি Sams একই রেসটি গড়ে 6 miles per hour বেগে দৌড়ায়, তাহলে Sams, Sharif-এর চেয়ে কত minutes বেশি সময় নিয়ে রেসটি শেষ করবে? সমাধান: *Sharif-এর সময় নির্ণয়: -সময় = দূরত্ব ÷ গতি -Sharif-এর সময় = 2 miles ÷ 8 miles per hour = 0.25 ঘণ্টা = 15 minutes *Sams-এর সময় নির্ণয়: -Sams-এর সময় = 2 miles ÷ 6 miles per hour = 0.33333 ঘণ্টা = 20 minutes *সময়ের পার্থক্য: -পার্থক্য = Sams-এর সময় - Sharif-এর সময় -পার্থক্য = 20 minutes - 15 minutes = 5 minutes -সুতরাং, Sams, Sharif-এর চেয়ে 5 minutes বেশি সময় নিয়ে রেসটি শেষ করবে। সঠিক উত্তর: (E) 5 minutesRelated 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-
