Mathematics � 3 months ago. Algebra Help! upstream and downstream word problems? Evelyn and Meridith decided to kayak 1 mile up and then back in the Humboldt channel. The rate of the water flowing in the channel was 2 miles per hour.� The downstream rate will have an overall rate faster than the boat in still water since the flow of the water speeds them up: R = b + w (boat and water Upstream Downstream River Boat Problems In English rate). Then the upstream rate is the same except the water rate slows down the boat, so: r = b - w. If we substitute those back into our two base equations, we now have: d = rt and D = RT. d = (b - w)t and D = (b + w)T. Now that we have the equations set up, let's see what the problem says. The distance is 1 mile from the start, then back to the beginning, so: d = D = 1. Free Math Help. Intermediate/Advanced Algebra. Word problems: boat (upstream, downstream), bike (slow, fast). Thread starter happiness. Start date Nov 19, � Paddle Boat You paddle boat 8 miles upstream(against the current) and 8 miles downstream(with the current). The speed of the current is 1 mile per hour. a. Write an equation that gives the total travel time t (in hours) as a function of your average speed r(in miles per hour) in still water. b. Find your total travel time if your average speed in still water is 3 miles per hour. c. How much faster is your total. Inconsistent Downstream and Upstream Problem. Ask Question.

If the rate of the water is 8 kph, what is the rate of the boat in still water? Correct answer is 40kph. Considering the following formulas: v $\leftarrow$ speed of boat. x $\leftarrow$ speed of river. v-x is for upstream. v+x is for downstream.

The rate of the water flowing in the channel was 2 miles per hour. The total time it took them to kayak up and back was 3 hours and 40 minutes. Assuming they were padding their kayak at a fairly consistent rate find the rate Evelyn and Meridith were paddling?

The downstream rate will have an overall rate faster than the boat in still water since the flow of the water speeds them up:. The total time ws 3 hours and 40 min. We need this in terms of hours so the minutes become a fraction of an hour to get:. What's left is a system of two equations and two unknowns. I'll start by solving the first equation for t in terms of b:. This is what the question asked for. If we wanted to know the time we could solve for "t" and "T", but we've not been asked to do that, Boat Travel Upstream And Downstream Problems Apk so I'll leave this at that.
