Answer: Swing twice as fast
Explanation: If superman wants to get a lot of kinetic energy he should swing fast. Kinetic energy is the energy of motion/movement so that means the more you do something fast the more KE you will get and if you do something twice as fast then you will gain more kinetic energy.
You have to subtract 4 from 7 and then add 5 and 3 then add 8 and 2 then multiply 10 with 3 to get 30.
