Answer:
The answer, also the only answer, is C.
Step-by-step explanation:
A: 20 is 1/2 of 40, so you would arrive at Seneca Falls in half an hour.
B: Same as a, 2 is 1/2 of 4, so you would also arrive to school in half an hour.
C: 60 is double 30, so it would take two hours to get from Albany to New York City.

Answer:
<h3> 78%</h3>
Step-by-step explanation:
Given
Number of scientist that line in Antarctica during the winter = 1,100
Amount of scientist in the summer = 5,000
Increment = 5000 - 1100
Increment = 3900
percentage change = Increment/Original amount * 100
Percentage change = 3900/5000 * 100
Percentage change = 3900/50
Percentage change = 78%
<em>Hence the percent change in the number of scientists living in Antarctica is 78%</em>
