Question

Three commercials are played in a row between songs on the radio. The three commercials fill exactly 3

Answer 1

According to the information given, it is found that the third commercial was 1.233 minutes long.

How is the time divided?

• The total time is of 3 minutes.

• The first commercial uses $\frac{1}\frac{1}{6} = \frac{1} + \frac{1}{6} = \frac{7}{6}$ minutes.

• The second commercial uses $\frac{3}{5}$ of a minute.

• The third commercial uses x minutes.

The sum of the time used by the three commercials is 3, hence:

$\frac{7}{6} + \frac{3}{5} + x = 3$

$\frac{35 + 18 + 30x}{30} = 3$

$53 + 30x = 90$

$30x = 37$

$x = \frac{37}{30}$

$x = 1.233$

The third commercial was 1.233 minutes long.
