Step-by-step explanation:

Answer:
38.5
Step-by-step explanation:
Answer:
45.6 mph
Step-by-step explanation:
Well,
If Bird A is EXACTLY 5 times as fast as Bird B, then it can reach 228 mph and Bird A can only reach 45.6 mph.
slope (m ) =
, y - 1 =
( x - 2)
The equation of a line in ' point- slope form 'is
y - b = m (x - a)( m is the slope and (a , b ) a point on the line )
To calculate m use the ' gradient formula'
m = (y₂ - y₁ )/(x₂ - x₁ )
let (x₁, y₁ ) = (2 , 1) and (x₂, y₂ ) = (14 , 31) ← values chosen from table
m = (31 - 1 )/(14 - 2 ) =
= 
equation in point- slope form using m =
and (a,b )= (2 , 1)
y - 1 =
( x - 2)
70-40= 30
30/2 = 15
40/2= 20
15 x 20 = 300
