Answer:

28.7 minutes on Thursday
3.3 minutes were saved

Step-by-step explanation:

R1·T1 = (69 mph)(32 min) = 2208 (mi·min/h)

R2·T2 = 2208 (mi·min/h) = (77 mi/h)·T2

T2 = 2208/77 min ≈ 28.7 min . . . . . travel time on Thursday

What is the area?? Please help

Olegator [25]

Answer:

Step-by-step explanation:

We have the triangle and the rectangle.

The formula of an area of a triangle:

$A_{\triangle}=\dfrac{1}{2}bh$

b - base

h - height

The formula of an area of a rectangle:

$A_{\boxed{\ }}=lw$

l - length

w - width

We have b = 24 ft, h = 7 ft, l = 24 ft and w = 10 ft.

Substitute:

$A_\triangle=\dfrac{1}{2}(24)(7)=(12)(7)=84\ ft^2$

$A_{\boxed{\ }}=(24)(10)=240\ ft^2$

The area of the figure:

$A=A_{\triangle}+A_{\boxed{\ }}$

Substitute:

$A=84+240=324\ ft^2$
