Alex skies 3 miles north, 2 miles east, 4 miles north, 13 miles east. How far would he have skied if he were able to go in a straight line from his starting point to his destination?
.
Both times he goes north and then east. So he takes 90 deg turn
tOTAL DISTANCE HE TRAVELS NORTH = 7 MILES
TOTAL DISTANCE HE TRAVELS EAST = 15 MILES.
Shortest distance will be the hypotenuse of a right triangle
7^2 +15^2
=49 +225
=274
sqrt 274 is the distance
= 16.5 miles
