Answer:
Explanation:
Ok so for motion problems like this, the formula is d=rt. Distance equals rate times time. So his ship travels at 15 km per hour and he has to travel 2865 km. So you need to take the rate which is 15 km and the distance which is 2865 km and divide. 2865 divided by 15, which is 191. So it will either be 191 days or 191 hours.
