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 [tex]9x[/tex].
According to question , total distance travelled in trip is equal to 600 miles .
Therefore , the expression for this [tex]x+9x=600[/tex]
Hence,[tex]10x=600[/tex]
implies that x=[tex]600/10[/tex]
[tex]x=60[/tex]
Distance travel by an automobile is 60 miles .
therefore ,the man distance travel =[tex]9*60=540[/tex].
