Question

10. A boat traveled 4 miles due cast away from a dock Then it turned and traveled 5 miles due seeth. Finally, it turned again and traveled back to the 3d 33 shown in the ligure kom. Viha of the following closest to the total Jinance the hour traveled? 3 13 miles D 18 miles

Answer 1

The travel of the boat has a shape of a right angle triangle

To find the total distance, first, we will find the length of the hypotenuse

So, as shown and using the Pythagorean theorem the hypotenuse will be =

`\sqrt[]{4^2+5^2}=\sqrt[]{16+25}=\sqrt[]{41}=6.4`

So, the total distance = the perimeter of the triangle =

`4+5+6.4=15.4`

Rounding to the nearest mile

So, the answer will be option C) 15 miles
