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
