Ineed to know what the statement means , plz !

Cody started biking to the park traveling 15 mph, after some time the bike got a flat so cody walked the rest of the way, traveling 4 mph. if the total trip to the park took 6 hours and it was 46 miles away, how long did cody travel at each speed? solve using rate times time= distance

15m is what percent of 60m; 3m; 30m; 1.5 km? the last one is km not m
