Answer:
30 days(To the nearest tenth of a day)
Explanation:
In this question, we are asked to give the number of days that a baby whale had grew to a size given the rate at which it grows per day.
We have been told that after the first day, it started growing to a point of 47.075 inch at a rate of 1.5 inch a day.
The number of days taken for this growth can be calculated by dividing the present size by the daily growth rate.
Mathematically, that is 47.075/15 = 31.38333
Now, we are told to convert this to the nearest tenth of a day. The value here should thus be 30.
