See more water and wind current word problem examples solved by the Algebra Word Problem Solver.
- Speed in still water, Current speed, Time difference: Find Times Upstream, Downstream.
- Still water speed and water current speed is given.
- Upstream / Downstream time relationship.
What You Enter
A motorboat can travel 25 miles per hour in still water. If it travels in a river which flows at a speed of 5 miles per hour, how far will it travel downstream in 5 hours, and upstream in 5 hours.
What You Get
Given: Upstream Time = 5 HOURS Given: Downstream Time = 5 HOURS Given: V = Speed in still water = 25 MPH Given: V = Speed of Current = 5 MPH Let U = Distance Travelled Upstream Let D = Distance Travelled Downstream U = (V-C) * UpstreamTime U = (25 - 5) * 5 U = 100 MILES Upstream U = (V+C) * DownstreamTime D = (25 + 5) * 5 D = 150 MILES Downstream
Solution: D = 150 MILES Downstream
Solving Water/Air Current Word ProblemsWhere the Still Water Speed and DCurrent Speed are given.
Variables:- V = Speed in Still water
- C = Speed of current
- (V + C) = Downstream_Speed
- (V – C) = Upstream_Speed
- (V + C) * Downstream_Time = Downstream_Distance
- (V – C) * Upstream_Time = Upstream_Distance
