Stocks and Shares

Practice Surds and Indices – A racehorse starts chasing a wild pony 3 hours after the pony bolts the stable. The pony runs through the entire country of Alb. Texas jumping 3 streams and crossing four 10 meter roads. The racehorse finally catches up with the pony after four hours by the time the sun had set and the moon was up in the sky for 4 hours. If the average speed of the racehorse is 73kmph then average speed of the wild pony is?

Practice Stocks and Shares – The speed of a boat in still water is 10 km/hr. The stream has a current of 2km/hr. The boat takes 2 hours more to cover a trip from A to B than it took to go from B to A. What is the distance between A and B?

Practice Stocks and Shares – A boat can travel 12.8 km downstream in 32 minutes. If the speed of the water current is (frac{1}{5}) th of the speed of the boat in still water, what distance (in km) the boat can travel upstream 135 minutes?

Practice Stocks and Shares – A boat takes 19 hr. for travelling downstream from point A to point B and coming back to a point C midway between A and B. If the velocity of the stream is 4 km/hr. and the speed of the boat in still water is 14 km/hr., what is the distance between A and B ?

Practice Stocks and Shares – A boat travels from A to B upstream and then from B to C downstream taking the same time. The respective ratio between the distance from A to B and the distance from B to C is 5 : 7. If the boat takes 2 hours 30 minutes to travel a distance of 35 km downstream, what is the speed of the stream ? (in km/hr.)

Practice Stocks and Shares – The speed of a boat in still water is 15 km/hr and the rate of current is 3 km/hr the distance travelled downstream in 12 minutes is :

Practice Stocks and Shares – A man can row upstream at 8kmph and downstream at 13 kmph. The speed of the stream is

Practice Stocks and Shares – A man travels by a motor boat down a river to his office and back. With the speed of the river unchanged, if he doubles the speed of his motor boat, then his total travel time gets reduced by 75%. The ratio of the original speed of the motor boat to the speed of the river is

Practice Stocks and Shares – A man takes 3 hours 45 minutes to row a boat 15 km downstream of a river and 2 hours 30 minutes to cover a distance of 5 km upstream. Find the speed of the current.

Practice Stocks and Shares – In a stream running at 2 kmph,a motar boat goes 6 km upstream and back again to the starting point in 33 minutes. Find the speed of the motarboat in still water.

Practice Stocks and Shares – 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?

Practice Stocks and Shares – A man can row a distance of 5 km in 60 min with the help of the tide. The direction of the tide reverses with the same speed. Now he travels a further 20 km in 10 hours. How much time he would have saved if the direction of tide has not changed?

Practice Stocks and Shares – A man can row 50 km upstream and 72 km downstream in 9 hours. He can also row 70 km upstream and 90 km downstream in 12 hours. Find the rate of current.

Practice Stocks and Shares – A man can row with a speed of 15 kmph in still water. If the stream flows at 5 kmph, then the speed in downstream is?
