| The depth of one pit is 4.8 more than the second, if the depth of the second pit is doubled, then its depth will be 1.2 m more than that of the first, find the depth of each pit.
Let us denote the depths of the first and second pits by A and B.
Since the depth of the first pit is 4.8 more than the depth of the second pit, we can draw up the equation:
A = B + 4.8.
If the depth of the second pit is increased by 2 times, then its depth will be 1.2 more than the depth of the first pit. Therefore, we can compose the second equation:
2 * B = A + 1.2.
Then we have:
2 * B = A + 1.2 = B + 4.8 + 1.2 = B + 6,
B = 6.
Then we can calculate the depth of the first pit:
A = B + 4.8 = 6 + 4.8 = 10.8.
Answer: 10.8 and 6.
