Tia travels 60 miles on Monday.
Step-by-step explanation:
Total distance = 90 miles
Let,
Distance on Monday = x
Distance on Tuesday = x/2
According to given statement;
[tex]x+\frac{x}{2}=90[/tex]
Solving the equation for the value of x;
[tex]\frac{2x+x}{2}=90\\[/tex]
Multiplying both sides by 2;
[tex]3x=180\\x=\frac{180}{3} \\x=60[/tex]
Tia travels 60 miles on Monday.
