75 – 18 × 80 ÷ 16 + 40 = 125 75 + 18 × 80 ÷ 16 – 40 = 125 75 + 18 × 5 – 40 = 125 75 + 90 – 40 = 125
The speed ratio of a stream to the upstream speed of a boat is 1:9. A boat takes 2 hours and 30 minutes to travel 82.5 km downstream. Determine the time...
The speed of Boat is given as 20 km/hr and 28 km/hr while travelling to Upstream and downstream individually.Then, the boat travelled for ‘T’ hours ...
A boat can cover ‘y’ km distance downstream in (t+2.5) hours. The same boat can cover ‘0.25y’ km distance upstream in ‘t’ hours. The time ta...
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 8:5:2, respectively. If ...
A boat can cover 145 km in downstream in 5 hours and 144 km in upstream in 8 hours. Find the speed of boat in still water.
A boat can travel 24 km upstream and 30 km downstream in 4 hours. Find the speed of the boat in still water if the speed of the stream is 3 km/h.
The speed of a boat in downstream is 20% more than speed of boat in still water. If the boat travels a distance of 90 km upstream in 15 hours then find...
In still water, a boat can cover 30 km in 90 minutes. Speed of the stream is 20% of the speed of the boat in downstream. Find the time taken by the boat...
Boat ‘A’ can cover 240 km in still water in 12 hours. In still water, if the ratio of the speed of boat ‘A’ to that of ‘B’ is 4:7 and the sp...
A boat can cover 140 km in downstream in 14 hours and 96 km in upstream in 12 hours. Find the distance travelled by the boat in still water in 5 hours.
