Acruise ship can sail 31 mph in calm water. sailing with the gulf stream, the ship can sail 288 mi in the same amount of tie it takes to sail 208 mi against the gulf stream. find the rate of the gulf stream

5 mph

The relationship between distance, speed, and time is ...

... time = distance / speed

If we let g represent the speed of the Gulf Stream current (in mph), the speed of the ship with the current is 31+g, and the speed against the current is 31-g.

The times for the two distances are equal, so we can write ...

... 288/(31+g) = 208/(31-g)

Multiplying by the product of the denominators gives ...

... 288(31 -g) = 208(31 +g)

... 31(288 -208) = g(208 +288) . . . . . add (288g - 208·31)

... g = 2480/496 = 5 . . . . . . . . . . . . . divide by the coefficient of g

The rate of the Gulf Stream is 5 mph.

step-by-step explanation:

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
