Question

A boat in calm seas travels 13km east and 35 km north. Find the distance and direction of the trip, relative to to the north.

Answer 1

Pythagorean Theorem :

c ^ 2 = a ^ 2 + b ^ 2

c = sqrt ( a ^ 2 + b ^ 2 )



c = sqrt ( 13 ^ 2 + 35 ^ 2 )

c = sqrt ( 169 + 1225 )

c = sqrt ( 1394 )

c = 37.336 km
