Answer :
The nonstop trip from Stein to Constance will take 48 minutes.
What is distance?
Distance is the sum of an object's movements, regardless of direction. Distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.
Let us suppose the distance between Stein to Constance as d:
Then according to the distance formula, we have:
Distance = Speed * Time
Now, let the velocity of boat be v, and the velocity of water be x.
To go from Stein to Schaffhausen it takes 40 minutes. This is represented as:
d = (v + x) (40) equation 1
To go from Schaffhausen to Stein it takes 60 minutes, this is represeted as:
d = (v - x)(60) equation 2.
Divide the equation 1 and equation 2 wegwt thw following:
3v - 3x = 2v + 2x
v = 5x
Substitute this value in the distance formula:
d = (5x + x) (40)
d = 240x
d/ x = 240
X can be written as v/5, substitute this value in the above equation we have:
d/ v = 48 minutes.
Hence, nonstop trip from Stein to Constance will take 48 minutes.
