Answer:
The answer to your question is it is stretched
Step-by-step explanation:
See the graph below
As you can see in the graph, the amplitude of the function y = sinx goes from -1 to 1, if the amplitude if higher, then it will be stretched in the example of this problem, the amplitude is 3, so it goes from -3 to 3.
If the amplitude were lower than 1, for example, 0.5, the graph will be compressed.

Answer:
182 seconds
Step-by-step explanation:
Given:
Time taken for first lap is 50 seconds and each subsequent lap takes 20% longer than previous
Solution:
Time taken for first lap = 50 sec
For second lap
Each subsequent lap takes 20% longer than previous
Previous lap time = 50 sec
second lap = 50 + 20% of 50
second lap
second lap
second lap
For third lap
Each subsequent lap takes 20% longer than previous
Previous lap time = 60 sec
Third lap = 60 + 20% of 60
Time taken for 3 laps is equal to sum of all three laps time.
Therefore, it takes 182 seconds (3 min, 2 seconds) to run three laps
