I have problems with word problems. 
Suppose you travel north for 35 kilometers 
then travel east 65 kilometers. How far 
are you from your starting point? North and 
east can be considered the directions of the 
y- and x-axis respectively. Round to the 
tenth's place.

Thank you

C² = A² + B²

C² = 35² + 65²

C² = 1225 + 4225

C² = 5450

 C = Ö5450

 C = 73.8241153

Round to the tenth place:

 C = 73.8
