His total trip was 600 miles in length. How far did he travel by plane? x represents miles by . 9x represents miles by .

Answer 1

Answer:

240 miles.

Step-by-step explanation:

Let a man travelled  by an automobile=x miels

and a man travelled distance  by an airpalne  was 9 times the distance travelled by an  automobile. Therefore, the expression is $9x$.

According to question , total distance travelled in trip is equal to 600 miles .

Therefore , the expression for this $x+9x=600$

Hence,$10x=600$

implies that x=$600/10$

$x=60$

Distance travel by an automobile is 60 miles .

therefore ,the man distance travel =$9*60=540$.

Answer 2

X represents miles by automobile

9x represents miles by airplane
