Answer:
1 milliliter is 20 drops.
I'm not sure if this is correct but you would put it into an equation while you solve for X. so 0.75x=150 or equivalently would be like (3/4)x=150 Then after that you would divide both sides by 0.75 or 3/4
move all terms to the left side and set equals to zero. then set each factor equal to zero
The answer to your question is C.
therefore, the actual distance is 280 miles.
(sorry, idk the rule for it)
