Answer:
42mph.
Step-by-step explanation:
We know that the formula for miles per hour is.
r = d/t
R is our rate or miles per hour.
D is our distance.
T is our time.
In this case our distance is 105 miles.
And our times is 2.5 hours.
Therefore if we substitute them into our formula:
105mi ÷ 2.5hrs = 42mph
Hope this helped!
( 0, 8 ) → B
Apply the given rule to the coordinates of point B (2, 5 )
thus B' = ( 2 - 2, 5 + 3 ) = (0, 8 )
Answer:
if you need distance then
Step-by-step explanation:
speed = distance /time
so
135=x/8
135x8=x
1080=x = distance
I'll help with a few.
3. -3x^3 - 9x^2 + 3x
Solve:
= (-3x)(x^2 + 3x + -1)
= (-3x)(x^2)+(-3x)(3x)+(-3x)(-1)
= -3x^3 - 9x^2 + 3x
7. (m - 2) (m + 11)
8. (t - 2) (5t + 9)
9. (5x + 3) (5x - 3)
10. (3t + 2)^2
