Answer :
Final answer:
The sailboat will reach its destination at 23:33 or 11:33 PM, after traveling for 10.2 hours at an average speed of 50 mph over a distance of 510 miles, starting from 13:15 or 1:15 PM.
Explanation:
To calculate the time it will take for the sailboat to reach its destination, we can use the formula time = distance ÷ speed. Given an average speed of 50 mph and a distance of 510 miles, the sailboat's travel time can be found as follows:
- Time = 510 miles ÷ 50 mph = 10.2 hours
The sailboat began its trip at 13:15, or 1:15 PM. Therefore, to find the arrival time, we must add the travel time to the departure time:
- Start time: 13:15 (1:15 PM)
- Travel duration: 10.2 hours
- Arrival time: 13:15 + 10:2 hours = 23:33 (11:33 PM)
Thus, the sailboat would reach its destination at 23:33 or 11:33 PM.
