BOATS AND STREAMS 1. A man can row against the current three - fourth of a kilometre in 15 min and returns same distance in 10 min, then ratio of his speed to that of current is 1) 2:5 2) 1:4 3) 1:5 4) 4:1 5) 5:1 2. A boat goes 52 km downstream in 20 h. It takes 6h more to cover the same distance against the stream. What is the speed of the boat in still water? 1) 1.3 km/hr 2) 3.6 km/hr 3) 3.2 km/hr 4) 6.4 km/hr 5) 2.3 km/hr 3. Pradeep can row downstream at 11 km/hr and upstream at 7 km/hr. Find the speed of Pradeep in still water and speed of current? 1) 9 km/hr and 2 km/hr 2) 6 km/hr and 1 km/hr 3) 7 km/hr and 2 km/hr 4) 9 km/hr and 1 km/hr 5) 8 km/hr and 3 km/hr 4. The speed of a boat in still water is 15 kmph and the rate of current is 13 kmph. Find the distance travelled downstream in 15 minutes. 1) 8 km 2) 7 km 3) 28 km 4) 21 km 5) 14 km 5. Surya can row 60 km downstream and 36 km upstream, taking 10h each time. What is the velocity...
