initial distance = 1000 feet
1 day = 3/5 x 1000
= 600 feet
Remaining distance = 1000 - 600
= 400 feet
2nd day = 3/5 x 400
= 240 feet
Remaining distance = 400 - 240
= 160 feet
3rd day = 3/5 x 160
= 96 feet
Remaining distance = 160 - 96
= 64 feet
4th day = 3/5 x 64
= 38.4
Remaning distance = 64 - 38.4
= 25.6
therefore the remaining distance to the ocean after 4 days of travel = 30 ( to the nearest tenth place).
