TIME, SPEED AND DISTANCE Boat 2

Rakesh and Siddharth row on a river simultaneously from the same point. Rakesh rows downstream and Siddharth rows upstream. In 15 min, they are 2.25 km apart. Rakesh then turns to follow Siddharth and after 30 min from the beginning, the boats have rowed together 3.5 km, if the speed of Rakesh, Siddharth and stream are constant at how many km/hr stream flows? c. 5 d. 2.5 (Question by Satyajit) A boat while going downstream, passes a floating wooden block. After 1.5 hr, the boat reaches bank of river and immediately turns back. After moving for 1 hour, the boat crosses that wooden piece again at a point which is 10 km ahead of the place where it was found earlier. Find the speed of stream in km/hr. 4 b. 3 d. 2.5 A man rowing upstream in a river accidently dropped his hat into the river. After travelling a distance of 30 m, he noticed it and immediately turned back to search for it. He found his hat after it had covered a distance of 20 m. If the speed of stream was r percent of the speed at which he rows in still eater, find value of r a. 20 b. 30 c. 25 d. 12.5
