$1280^{\circ}$

Work Step by Step

1.Given 320 rotations per minute, change it into degrees per minute by multiplying it by 360 degrees $360\times 320=115200^{\circ}$per minute 2. Devide by 60 to find degrees per second $115200 \div 60 = 1920^{\circ}$ per second 3. To find rotations in 2/3 of a second, multiply by factor 2/3 $1920\times\frac{2}{3} =1280^{\circ}$
