√10201 × √3969 - (52)² = √? + (60)² => 101× 63 - 2704 - 3600 = √? => ? = 59× 59 => ? = 3481
A boat can cover 220 km in downstream in 10 hours and 170 km in upstream in 17 hours. Find the distance travelled by the boat in still water in 5 hours.
A boat goes 65 km in upstream in 5 hours and takes 4 hours to complete a distance of 20 km in downstream. Find the speed of boat in still water.
The speed of current is 18 km/hr. If the speed of the boat in still water had been 7 km/hr more than the original speed, then it would take 8 hours to c...
A boat running downstream covers a distance of 24 km in 3 hrs while it covers the same distance upstream in 6 hrs. Then speed of the boat in still water is
The ratio of the speed of boat ‘A’ in still water, the speed of boat ‘B’ in still water and the speed of the current is 6:4:2, respectively. If ...
Speed of a boat in still water to speed of boat in upstream is 13:10. If the boat can travel 320 km in downstream in 5 hours, then find the time taken b...
Two boats X and Y start towards each other from two places, 155 km apart. Speed of the boat X and Y in still water are 14 km/hr and 17 km/hr respectivel...
A boat covers 24km upstream and 36km downstream in 6 hours while it covers 36km upstream and 24km downstream in 13/2 hours. The speed of the current is....
A man goes downstream with a boat to some destination and returns upstream to his original place in 5 hours. If the speed of the boat in still water and...
Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 25 minutes to cover 50 km in downstream, then find th...
