Web15 nov. 2024 · Speed going upstream is 30mph (150 / 5). Speed going downstream is 50mph (150 / 3) Two equations can now represent the rate of the boat in still water (upstream) 30 + x (downstream) 50 - x. Set the two equations equal to each other. 30 + x = 50 - x; Combine like terms and solve for x. 2x = 20; x = 10 (rate of current) WebAnswer (1 of 3): * Let S denotes the required speed (in km/hr) of the boat in still water. * Hence from above data we get following relation, * * (S + 2 km/hr)*(4 hrs) = (S - 2 km/hr)*(5 hrs) [= constant distance between the two given ports] * or (5 hrs - …

WebQuestion 933488: A boat going upstream (against the current) travels 105 miles in 15 hours. It takes the same boat 7.5 hours to make the same trip when it is traveling back down stream (with the current). What is the speed of the boat in still water and what is the speed of the current of the river? Answer by mananth(16163) (Show Source): WebThe boat covers either 36 km in 3 hours going downstream or it covers 24 km in 3 hours going upstream. Formula used: Going along the stream, resultant speed = speed of the boat in still water + speed of the stream. Going against the stream, resultant speed = speed of the boat in still water - speed of the stream. Calculations:
