A boat traveled 12 miles north and then

22.5 miles east. What is the shortest
distance the boat must travel to return
to its starting point?

Answer 1

25.5 mi

Explanation:

12 22.5 X

Let X be the shortest distance we are trying to find.

a units 2 b units 2 c units 2

12 units 2 + (22.5)=c units 2

144+506.25=c units 2

650.25=c units 2

`√(x) 650.25`=c units 2

25.5
