1. identify the phrase that does not represent the same rate as the other two. * *
(a)36 miles per hour
(b)3,158 miles per minute
(c)52.8 feet per second

Just convert them to the smallest unit possible which is seconds
1 hour=60 mins
1 min=60 seconds
1 hour=3600 seconds

1 mile=5280 feet
so 36 miles per hour =
36 times 5280 feet per 3600 seconds so
36 times 5280=190080 then divide by 3600=52.8 feet per second

then 3158 miles per minute or
5280 times 3158 divided by 60 so
5280 times 3158=16674240 then divide by 60= 277904 feet per second

so A=52.8 feet per second
B=277904 feet per second
C=52.8 feet per second

B is obviously the odd one out so B is the answer
