60 minutes in 1 hr, 60 seconds in 1 minute....(60 * 60) = 3600 seconds in 1 hr
(1/4) / 36 = x / 3600...1/4 mile to 36 seconds = x miles to 3600 seconds
cross multiply
(36)(x) = (1/4)(3600)
36x = 900
x = 900/36
x = 25 mph <==

H₁ = The local pizza takes less time than the chain.
H₀= The local pizza takes more time than the chain.
Step-by-step explanation:
Since you want to know if the advertisement by the local pizza restaurant ("It delivers to the dormitories faster than a local branch of a national chain") is true, the hypothesis to be performed is

H₀= The local pizza takes more time than the chain.
The approximate width of Alice's backyard is 22.36 in.
Let l be the length of the rectangle and w be the width.
l = 2w
A = 1000 m2 = l*w
1000 m2 = 2w *w
500 m2 = w^2
√500 m2 = √w^2
w = <span>22.360679775 in or 22.36 in</span>
