You start driving north for 3 miles, turn right, and drive east for another 4 miles. At the end of driving, what is your straigh

nalin [4]

The straight line distance is 5 miles from starting point.

Step-by-step explanation:

Driving 3 miles north and 4 miles east and then the straight line distance will form a right angled triangle.

Where;

One leg = a = 3 miles

Other leg = b = 4 miles

Hypotenuse = c

Using Pythagoras theorem;

$a^2+b^2=c^2\\(3)^2+(4)^2=c^2\\9+16=c^2\\c^2=25$

Taking square root on both sides

$\sqrt{c^2}=\sqrt{25}\\c=5$

The straight line distance is 5 miles from starting point.

8 minutes longer will be the correct answer!

Step-by-step explanation:

First, let's find out how many minutes Gabriella played:
