Sagot :
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
