One warehouse has 185 tons of coal, and another 237 tons. The first warehouse released 15 tons of coal every day, and the second – 18 tons. In how many days will there be 1.5 times more coal in the second warehouse than in the first?

Let’s compose a system of equations:

1.5 * (185 – 15x) = (237 – 18x), where x is the number of days.

Let’s transform the expression:

277.5 – 22.5x = 237 – 18x;

40.5 = 4.5x;

x = 9.

Answer: the second warehouse will have one and a half times more coal in 9 days.
