Mark is playing baseball after school. He wants to find the total distance he will need to ride his bike from school to the park

Ymorist [56]

Use the distance formula (derived from Pythagorean Theorem:
$d = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } \\ = \sqrt{ {(10 - 8)}^{2} + {(11 - 7)}^{2} } \\ = \sqrt{ {(2)}^{2} + {(4)}^{2} } = \sqrt{4 + 16} \\ d = \sqrt{20}$
$d = \sqrt{20} = \sqrt{4} \times \sqrt{5} = 2 \sqrt{5}$
