Problema Solution
A boat travels 80 feet across a river. The current then pushes the boat downstream 39 feet. How far is the boat from its starting point?
Answer provided by our tutors
Let 'd' represent the distance from the starting point.
Using the Pythagorean Theorem we have:
d^2 = 80^2 + 39^2

d = 89 ft
We need to ignore the negative solution since the distance can only be positive.
The boat is 89 feet far from the starting point.
