In the question, it is already given that the total number of runners in the race is 60 and out of them 1/3 dropped out in the first half. In the second half 1/4 of the remaining runners dropped out.
Now
Total number of runners in the race = 60
Number of runners that dropped out in the first half = 1/3 * 60
= 20
Number of runners remaining = 60 - 20
= 40
Number of runners dropping out in the second half = 40 * 1/4
= 10
Then the number of runners that finished the race = 40 - 10
= 30
Then 30 runners completed the race.

❖ The gray whale will need to come up 12 times during the 6 hr period.
Convert 6 hrs to mins:
1 hr = 60 mins
60 x 6 = 360 mins
Divide by 30 to see how many times the whale will need to come up:
360/30 = 12
