Question

You start driving west for 3 miles, turn right, and drive north for another 2 miles. At the end of driving, what is your straight line distance from your starting point? Round to the nearest tenth of a mile.

Answer 1

You can use pythagorean theorem. 3 miles would be one leg and 2 miles would be the other. (We’ll just call these two a and b in the formula. Letter c, also known as your hypotenuse, will be this ‘straight line distance’.) In order to find this you’ll use: a^2 + b^2 = c^2
Then you’ll find the square root of your sum to get the answer.

Answer: 3^2 + 2^2 = ?
9 + 4 = 13
the square root of thirteen will be about
3.61

Answer 2

Straights line distance is 3.6 mile

Given that;

Distance travel toward west = 3 mile

Distance travel toward north = 2 mile

Find:

Straights line distance

Computation:

Straights line distance is hypotenuse distance

c = √a² + b²

So,

Straights line distance is hypotenuse distance = √3² + 2²

Straights line distance is hypotenuse distance = √9 + 4

Straights line distance is hypotenuse distance = √13

Straights line distance is hypotenuse distance = 3.6 mile (Approx.)
