Thank you for the opportunity to help you with your question!

Let x = time of travel to appointment

then, x + 1/5 = time of return trip

Distance going = 60x

Distance returning = 50(x+1/5)

Distance going = Distance returning

therefore,

60x = 50(x+1/5)

60x = 50x + 10

10x = 10

x = 1 hour

therefore, distance traveled to appoint is

60(1) = 60 miles

Please let me know if you need any clarification. I'm always happy to answer your questions.
