Stu trained for a triathlon for 5 hours yesterday. he ran 5 miles and then biked 80 miles. his biking speed is 15 mph faster than his running speed. what is his running speed?

Step-by-step explanation:

Given as :

The distance cover while running = = 5 miles

Let The speed for running =

The distance cover with bike = = 80 miles

The speed for biking = = 15 mph +  

Total Time taken = 5 hours

Now Time =

∴ 5 hour = +  

Or,  5 hour = +  

Or, 5 hour =

or,  5 × () =

Or, -   = 0

or, = 0

or,   = 0

Or, = 0

Or, = 0

Or, = 0

∴ = 3 , - 5

So, the running speed = 3 mile per hour

And the biking speed = 15 mph + 3 mph = 18 mile per hour

Hence The running speed of Stu is 3 mile per hour  .  Answer

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 !
