A man was going on a one-way bus trip. He intended to ride for a certain distance, get off the bus and walk back to town.
If the bus travels at a rate of nine miles per hour and he was to jog back to town at a rate of three miles per hour, how far would he ride so that he'd be back in eight hours?

Answer
Eighteen miles. Since he is riding three times as fast as he can jog, three-quarters of his time must be spent jogging. Since he rode for two hours, travelling 18 miles, and jogged for six hours, travelling at three mph he made the round trip in eight hours.Hide Answer Show Answer

The question stated that what distance must he travel in the bus so he can jog back taking 8 hrs. If im wrong , please say something. The distance formula is d=r*t. i think it should be 24 miles. if he jogs at 3 mph, just plug it in the formula. d=3*8,
d=24.
d=24.
I believe it is intended to be total time.
That's not the point. The point is that 3 mph is a slow walk, not a jog. The average walking apeed is around 4 mph (faster in New York, and slower in LA, of course).
