Sagot :

Answer:

[tex]31\frac{2}{3}[/tex]

Step-by-step explanation:

since its only 2/5 of 1 hour, two 2/5 equal 4/5 so we divide the 12 2/3 by 2 to find the 1/5 which is 6 1/3

[tex]12\frac{2}{3}[/tex]÷2=[tex]6\frac{1}{3}[/tex]

[tex]12\frac{2}{3} +12\frac{2}{3}=25\frac{1}{3}[/tex]

[tex]12\frac{1}{3} +6\frac{1}{3}=31\frac{2}{3}[/tex]

The answer is 31 2/3
