Question
AB and AC are the two tangents to a circle whose radius
is 6 cm. If β BAC = 60o, then what is the value (in cm) of β(AB2Β + AC2)?Solution
A car can cover a β2dβ km distance at the speed of βBβ km/h in 30 hours. The speed of the boat in still water and the speed of the stream are οΏ½...
A man swims downstream 60 km and upstream 36 km, taking 12 hr each time. Find the manβs rate in still water?Β Β Β
The ratio of the speed of boat βAβ in still water, the speed of boat βBβ in still water and the speed of the current is 6:4:2, respectively. If ...
The speed of a boat in still water is 32km/hr and the speed of the current is 8km/hr. It takes a total of 15hours to row to upstream from Point A to B a...
Boat βAβ can cover 100 km in still water in 10 hours. In still water, if the ratio of the speed of boat βAβ to that of βBβ is 2:3 and the sp...
The speed of a boat in still water is 5 times more than that of the current. If the boat takes 10 hours to cover 200 km upstream, then find the time tak...
A boat travels faster than the stream by 28 km/h. It covers a distance of 112 km upstream and returns 132 km downstream, all within 7 hours. Calculate t...
- A boat takes a total of 6 hours to travel 45 km downstream and 30 km upstream. In another scenario, the same boat takes 8 hours to cover 60 km upstream and...
The speed of current is 25 km/hr. If the speed of the boat in still water had been 5 km/hr more than the original speed, then it would take 4 hours to c...
Ratio of still water speeds of three boats is 3:4:5. The first boat travels downstream, the second and third boats travel upstream. They travel in strea...
