A c-pole of 200ft is 250ft from the d-pole which is 150ft high..Two pigeons are sitting at the top of each poles(one in one pole)Both pigeon fly towards a grain which is present between the 2 polesat the same speed.what is the distance between the c-pole and the grain?
Two trains each 1/6 mile in length run in opposite dirctions to each other with equal speed of 60 miles/hour. What is the time taken to completelycross over the two trains.
Speed at which two trains travel towards each other = 60+60 = 120 miles/hour.Total length to be covered = (1/6)+(1/6) = 2/6 mile.Time to taken to cover 2/6 mile at speed of 120 miles/hour is.....(2/6)/120
A man wearing a hat stands on a bridge across a river. At an instant his hat falls into the river and starts flowing along with the stream at the same speed of the stream.At the same instant the man jumps into the river and starts swimming in the directionopposite to the stream, like that he swims for 10 minute , then he turns back and starts swimming in the direction of the stream to retrieve the hat. He retrieves the hatunder another bridge which is 1000 yards away down the stream from the first
Let the swimming speed of man be = a yds/min.speed of stream = b yds/min.Then the man swims at (a-b) yds/min. against the stream.and (a+b) yds/min in direction with the stream.Lets assume the man covered
A train travels at a particular speed for a duration of one hour, after which one of its engine malfunctions reducing its speed to 3/5th of the actual speed before theoccurrence of fault in engine. It travels at this speed for 2 hours to reach at itsdestination. If the fault had occurred 50 miles later on, the train would have reachedits destination 45 minutes early. Find the distance traveled by the train.
Let the actual speed of train be X miles/hour. after fault its speed will be reduced to 3X/5 miles/hour. If we could find the speed of the train, we will get the solution!!!by seeing one can find that
Albert and Fernandes have two leg swimming race. Both start from opposite and of the pool. On the first leg, the boys pass each other at 18 mt from the deep end of the pool. During the II leg they pass at 10 mt from the shallow end of the pool. Both go at const speed. But one of them is faster. Each boy rests for 4 sec to see at the end of the I leg. What is the length of the pool.
Two people X & Y walk on the wall of a go down in opposite direction. They meet at a point on one side and then go ahead. X after walking for some time, walks in opposite direction for 15 mtrs. Then again he turns back and walks in the original direction. What distance did Y walk before they met again, if X walks 11 mtrs by the time Y walks 8 mtrs.
Afly is there 1 feet below the ceiling right across a wall lengthis 30m at equal distance from both the ends. There is a spider 1 feetabove floor right across the long wall eqidistant from both the ends.If the width of the room is 12m and 12m, what distance is to be travelled by the spider to catch the fly? if it takes the shortest path.?
