Answer
$9360^{\circ}$
Work Step by Step
1.Given 650 rotations per minute, change it to degrees per minute by multiplying by 360 degrees
$650\times 360=234000^{\circ}$per minute
2. Devide by 60 to find degrees per second
$234000 \div 60 = 3900^{\circ}$ per second
3. To find rotations in 2.4 seconds, multiply by factor 2.4
$3900\times 2.4 =9360^{\circ}$
