Question

Tim rode 8 miles due north, then 3 miles due east. How far, to the

nearest mile, is Tim from where he started?

Answer 1

c = 8.54

Explanation:

Use Pythagorean theorem and sketch a right triangle with side lengths of 8 and 3, with the hypotenuse labeled as x.

Use the formula a² + b² = c²

8² + 3² = c² Plug in your two numbers into variable

64 + 9 = c² Simplify the squared numbers

73 = c² Add them together

√72 = c Divide the squared variable by using the opposite operation, square rooting

c = 8.54 Plug number into calculator and round
