A man drove x miles per hour for 3 hours and (2x-60) miles per hour for the next 4.75 hours. A)Express the total distance travel
erik [133]

Answer:

12.5x-285.

Step-by-step explanation:

We are told that a man drove x miles per hour for 3 hours, so he traveled 3x miles in three hours.

We are also told that he drove (2x-60) miles per hour for the next 4.75 hours. So The distance traveled by in next 4.75 hours will be:

4.75\cdot (2x-60)=9.5x-285  

To find the total distance traveled by man we will add distances traveled by him in first 3 hours and next 4.75 hours.

\text{The total distance traveled}=3x+9.5x-285

Upon combining like terms we will get,

\text{The total distance traveled}=(3+9.5)x-285

\text{The total distance traveled}=12.5x-285

Therefore, the total distance traveled in terms of x will be 12.5x-285.

That would be (1.10 C) , and that's the $856.90 .  

So the equation is . . . 1.10 C = $856.90

Divide each side by 1.10 : C = $856.90 / 1.10
