<u>Answer</u>
224 Km
4 Km
<u>Explanation</u>
<u>Part 1</u>
The plane flies 100 Km north and then 200 Km east. This makes a 90° turn. To get the distance taken by the plane we get the hypotenuse.
c² = a² + b²
c² = 100² + 200²
= 50,000
c = √50,000
= 223.606 Km
The answer to the nearest whole number is 224 Km
<u>Part 2</u>
If the runner run 15 Km north then 11 Km south, the resultant distance would be,
15 - 11 = 4 Km
It's the instantaneous speed. Average speed would take all the different speeds from the whole ride in order to fine the median or middle speed.
The current will increase at the same rate the voltage does.
Hi! I believe the correct answer is A. Do you have any other questions I can help you with? I would be glad too.
