eliminate
b) he can push the cart up a ramp.
c) he can take the wheels off the cart.
d) he can increase the force of his push.

D

Explanation:

A) He can add weight to the cart.

 If he added weight to the cart it would be harder to push, and probably slow it down.

B) He can push the cart up a ramp.

Pushing the cart up the ramp would require a lot of extra force. Going up a ramp would not make it faster.

C) He can take the wheels off the cart.

taking the wheels off the cart would make it EVEN  harder to move the cart...it would no go faster

D) He can increase the force of his push.

Increasing the force of the push at a speed rate will increase the speed

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
