Let A is the starting point and B is actual point where train started facing problems C is the assumed point train started facing problems Given BC = 15km and Difference of is 30 minutes basically due to the speed covering this 15km. Let original speed = x km/hr ∴ Speed after clutch problem = 2x/5 km/hr ⇒ 15/(2x/5) - 15/x = 30/60 ⇒ 75/2x - 15/x = 1/2 ⇒ (75 - 30 )/2x = 1/2 ⇒ (45 )/2x = 1/2 ⇒ x = (45 × 2)/2 ∴ x= 45 km/hr
Speed of a boat in still water to speed of boat in upstream is 12: 7. If the boat can travel 425 km in downstream in 5 hours, then find the time taken b...
The ratio of the speed of boats ‘A’ and ‘B’ in still water is 8:9, respectively. The speed of the current is 25% of the speed of boat ‘A’ in...
A boat travels upstream at a speed of 10 km/h and downstream at 15 km/h. If the boat travels 30 km upstream and then returns, how much time does it take...
The speed of a boat in still water is 12 km/h and the speed of the current is 3 km/h. A person travels 270 kilometers in a boat in the upstream directio...
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...
The time taken by a boat to cover 72 km downstream is 3 hours less than the boat to cover a certain distance in upstream. The dow...
A man can row at 36 km/hr in still water. In a stream which is flowing at 12 km/hr, it takes him 3 hrs to a place and back. How far is the place?
A boat can travel 10 km more in downstream than that in upstream, in 5 hours while the difference between the time taken by the same boat to travel 250 ...
A man can row his boat with the stream at 14 km/h and against the stream in 8 km/hours. Find the rate of the stream.
The ratio between the time taken by a boat to cover a certain distance in upstream and the same distance in downstream is 5:1 respectively. The same boa...
