The distance the fisherman rowed is 3.2 miles if the fisherman can row upstream at 1 mph and downstream at 4 mph.
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A fisherman can row upstream at 1 mph and downstream at 4 mph.
He started rowing upstream until he got tired and then rowed downstream to his starting point.
Let the time of row upstream is x hours
Let the time of row downstream be y hours
From the question:
x + y = 2
x = 2 - y
x = 4y
Solving the above two linear equations by substitution method:
2 - y = 4y
5y = 2
y = 2/5
y = 0.4 hours
Distance = speed×time
Distance = 4×0.4 = 1.6 miles
= 1.6×2 = 3.2 miles
Thus, the distance the fisherman rowed is 3.2 miles if the fisherman can row upstream at 1 mph and downstream at 4 mph.
