Answer:
Option D.
Step-by-step explanation:
So first you got to convert all the options into mi/hr then pick the highest one:
Steps:
456.5 mi/hr (dont do anything to this because it is already in mi/hr)
---------------------------------------------------------------------------------------------
0.3 mi/s (this one you got to multipy 0.3 by 3600 to find the mi/hr. the reason being is that there are 30 seconds in a minute and 60 minutes in an hour 60 x 60 = 3600)
---------------------------------------------------------------------------------------------
28 mi/hr (dont do anything to this because it is already in mi/hr)
---------------------------------------------------------------------------------------------
28 mi/min (this one you got to multiply 28 by 60 to find the mi/hr. The reason bing is that there are 60 minutes in an hour)
---------------------------------------------------------------------------------------------
Conversons:
456.5 mi/hr
---------------------------------------------------------------------------------------------
1080 mi/hr
---------------------------------------------------------------------------------------------
28 mi/hr
---------------------------------------------------------------------------------------------
1680 mi/hr
---------------------------------------------------------------------------------------------
Answer:
1680 mi/hr = 28 mi/min
So the answer is option D.
