Answer :
In order to answer this problem, we use our knowledge on ratio and proportions. From the problem, it is said the the the blue whale had traveled 6 times as far as the first time. This can be written as:
6 = second time / first time
6 = x / 495 feet
x = 2970 feet
6 = second time / first time
6 = x / 495 feet
x = 2970 feet
