I am practicing from a book with the answers but not the details, so I would like the step-by-step information so I can understand and learn. Could you help?
Q: ROUND TRIP SITUATION:
A man drove from his home to a distination and back again (along the same road) in 10 hours. His average speed going was 20 mph and on the return was 30 mph. How long did he take in each direction and what distance did he cover each way?
How do I show an equation here? And How do I solve this? I know (the book gives the answer) that 120 miles is the distance each way and 6 hours going and 4 hours returning. Please explain step-by-step.
Thank you,
