I think it is d not sure tho
im sorry but i know x=6 if that helps
Answer:
x= 6
Step-by-step explanation:
You can figure out how many miles per hour it travels by dividing 18/3. This gives us the answer of 6. 3/4 = 0.75 so we can multiply 6 * 0.75 to get 4.5 as our final answer. It will travel 4.5 miles in 3/4 of an hour.
