aalyn [17]

Answer:

$31\frac{2}{3}$

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

$12\frac{2}{3}$ ÷2= $6\frac{1}{3}$

$12\frac{2}{3} +12\frac{2}{3}=25\frac{1}{3}$

$12\frac{1}{3} +6\frac{1}{3}=31\frac{2}{3}$
