Question

a bird of species a when diving can travel four times as fast as a bird of species b top speed if the total speeds of these two birds is 180 miles per hour find the fastest speed of the bird species a and the fastest speed of species B

Answer 1

X will be the speed of species b and 4x will be the speed of species a:

x + 4x = 180
5x = 180
x = 180 / 5
x = 36 m/h

If species b has a speed of 36 m/h, the speed of species a is 4 times that:

4 x 36 = 144 m/h.


Answer:

$\boxed {\bf A~=~36~m/h~and~B~=~144~m/h}$
