Let \(x\) be the distance traveled to the city, then the time taken is given by
distance / speed \(=x / 60\)
and the time to return is given by
distance / speed \(=x / 50\)
The total time to travel and return is 5 hours. Hence
\(x / 60+x / 50=5\)
Solve for \(x\)
\(x=1500 / 11=136\) miles (rounded to the nearest mile)
