Answer 1

Problem Analysis

We are given that there were 38 tons of kerosene in a tank. On the first day, the amount of kerosene used was 2.4 times greater than the amount used on the second day. After these two days, there were 9.1 tons of kerosene left. We need to find out how much kerosene was used on the first day.

Solution

Let's assume that the amount of kerosene used on the second day is x tons. According to the problem, the amount of kerosene used on the first day is 2.4 times greater than x.

Let's set up an equation to represent the given information:

x + 2.4x = 38 - 9.1

Simplifying the equation:

3.4x = 28.9

Now, we can solve for x by dividing both sides of the equation by 3.4:

x = 28.9 / 3.4

Evaluating the expression:

x ≈ 8.5

Therefore, approximately 8.5 tons of kerosene were used on the second day.

To find the amount of kerosene used on the first day, we can multiply x by 2.4:

2.4 * 8.5 ≈ 20.4

Therefore, approximately 20.4 tons of kerosene were used on the first day.

Answer

Approximately 20.4 tons of kerosene were used on the first day.
