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 and B are two friends, together they go out for shopping. A buys a hat and a suit,all together A spends 15 rupees. B buys a hat which costs same as the suit bought byA. B even buys a dress which cost her one rupee less than the cost of hat bought by A.B says to A that "If at all I had bought my hat by spending one and half times the money u spent on buying your hat, we both would have spent the same amount on buying our items(together, i.e., 15 rupees).(a) what is the cost of hat bought by Lets say A spent x and y rupees on hat and suit respectively. from the conditions we can say B spent y and x-1 rupees on hat and dress respectively.

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 Old Man WrinkleMan Wrinkle spent one-fourth of his life as a boy, one-eighth as a youth, and one-half as an active man. If Man Wrinkle spent 8 years as an old man, then how many years did he spend as an active man? (1/4)y+(1/8)y+(1/2)y =p; where y =total life time.y-p=8.since p=(14/16)ywe've y=64active age=32
