After its first day of life, a baby blue whale started growing. It grew 47.075inch. If the average baby blue whale grows at a rate of 1.5inch a day, for how many days did the baby blue whale grow, to the nearest tenth of a day?

30 days(To the nearest tenth of a day)

Step-by-step 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.
