Question

Karen bicycles 4 miles west to get from her house to school. After school, she bicycles 5 miles north to her friend Monica's house. How far is Karen's house from Monica's house, measured in a straight line? If necessary, round to the nearest tenth.

Answer 1

6.4 miles

Explanation:

Pypthagorem Theorem:
`a^(2) +b^2=c^2`

a= 4 miles west

b= 5 miles north

a^2+b^2=c^2

4^2+5^2=c^2

16+25=c^2

41=c^2

c = 6.4
