The helicopter has to leave at 1:30 pm to meet the boat after 2 hours at the meeting point.
<h3>What is Speed ?</h3>
Speed is the distance covered by an object in a given amount of time.
It is measured in km/h or m/h.
According to the data in the question
If the boat goes to the station ,
Speed of the boat = 10mph
it will take 400/10 = 40 hours.
The helicopter has 6600 lbs of fuel.
For the 30 minutes to remove the fisherman and the 1 hour more fuel is needed, that will consume
1.5 *1200 = 1800 lbs of fuel.
the helicopter now has
6600-1800
= 4800 lbs of fuel for flying.
This will give it 4 hours of flying time as
4800 lbs/1200 lbs per hour
it can only fly one way for 2 hours at 150 mph
= 300 miles distance from the station.
The boat is at 400 miles
boat needs to reach the meeting point 300 miles away from the station.
which is 100 miles from where it is now
100/10 = 10 hours
the boat will need 10 hours to go to the meeting point.
To meet the boat , which will take 10 hours the helicopter must start flying after 8 hours as it will also take 2 hrs
So 8 hours from 5:30 am will be 1:30 pm
The helicopter has to leave at 1:30 pm to meet the boat after 2 hours at the meeting point.
