can someone help please

1. Need urgent help in how to calculate total cargo weight a ship carry.
2. A ship is expected to sail a distance of 3,200 n.m. at an average speed of 12

knots. Calculate her expected time of arrival if she departed on December 28,

2014 at 2200 hours.

hey there,

1:

Payload = Total displacement - light ship weight - provisions (fuel, lube oil, food,...) - ballast water

2:

Distance travelled: 3200 nm
Avg. speed: 12 kts = 12 nm/h

--> Time en route: 3200 nm/(12 kts * 24 h) = 11.11111 d.
