The distance between starting and ending point is 34 miles.
Step-by-step explanation:
Given,
Car moves 16 miles to north then 30 mile to east.
It forms a right angle triangle.
The straight line distance from starting to ending point represents hypotenuse.
To find the distance between starting and ending point.
Formula
By <em>Pythagoras theorem,</em>
h² = b²+l² where h is the hypotenuse, b is base and l is the another side.
Taking, b=16 and l=30 we get,
h² = 16²+30²
or, h =
or, h = = 34
Hence,
The distance between starting and ending point is 34 miles.
The answer is c.
a. (2.2≠5.11) (2.2 is not equal to 5.11)
b. or 0.625 (0.625≠5.11) (0.625 is not equal to 5.11)
c. (5.11=5.11) (5.11 is equal to 5.11)
Therefore c is the answer
