one ship sailing east with speed of 7.5m/s passes a certain point at 8A.m and a second ship sailing north at same speed,passed at 9:30A.m at what time are they closest together and what is the distance between them?
Answers
Answer:
there would be a distance of 40.5km between them
ANSWER:
The distance of the closeness between two ships is 40.5 km
The time both the ships are close is at 9:30 AM
EXPLANATION:
Let us draw a diagram for the easement of the users, the diagram for the two boats is
If we take the diagram after the first ship crosses the point at 8:00 AM, after that the most closest distance, the ship 2 can get to ship 1 is the straight line between the point and the ship, like in the scenario near it making the distance between the ship 2 and ship 1 as B’’’A.
Now after the point crossed by ship1 till ship 2 reaches that point is d, making the value of the distance as
D = Speed(S) x Time(T)
The value of the speed(S) = 7.5 m/sec
The time taken by the ship 2 to reach point B’’’ is 90 minutes or 5400 seconds
Therefore, the distance of the closeness between two ships is 40.5 km
The time both the ships are close is at 9:30 AM
