Question 110956This question is from textbook Algebra and Trigonometry
: the river boat Delta Duchess paddled upstream at 12km/h, stopped for 2 hours of sightseeing, and paddled back at 18km/h. How far upstream did the boat travel if the total time for the trip, including the stop, was 7 hours?
How do I set this problem up? This question is from textbook Algebra and Trigonometry
You can put this solution on YOUR website! distance=(rate)*(time) ... you need to find the times for the two parts of the trip and use them to find distance
let x="time upstream", so 5-x="time downstream" ... 12(x)=18(5-x)
