a kayaker travels x miles per hour downstream for 3 hours. on the 4-hour return trip, the kayaker travels 1 mile per hour slower. how far did the kayaker travel in total?
3x is the miles from downstream
4 (x - 1) is the return trip
Solution:
3x = 4 (x - 1)
3x =4x - 4
-x = -4
x = 4
The outward journey 3x = 12 miles
Return journey is same length
Therefore the distance travel is 24 miles
Answer:
The answer is 24 miles.
Step-by-step explanation:
We know that distance = rate * time
Length of the journey = \(3x\) from downstream
Length of the journey = \(4(x-1)\) from return trip
As the distance is same, we will equate both the journey lengths.
\(3x= 4(x-1)\)
Solving for x;
\(3x=4x-4\)
\(-x=-4\)
x = 4
Thus the forward journey, \(3x=3(4)\) = 12 miles.
Return journey will be of same length that is 12 miles.
The total distance traveled is \(12+12=24\) miles.
Therefore, the answer is 24 miles.
