Answer:
Equation;
584=H+2B
Rory and her cousin traveled 146 miles each
Explanation:
The total distance to be covered can be expressed as;
T=H+2B
where;
T=total distance to be covered
H=distance covered on the first day
B=distance covered by either Rory or her cousin on the second day
In our case;
T=584 miles
H=584/2=292 miles
B=b
replacing;
584=292+2×b
2 b=584-292
b=292/2=146 miles
Rory and her cousin traveled 146 miles each
