Best ResponseYou've already chosen the best response.2convert 42 mph in mps for that you can use this relation 42 miles  1 hour 60 minutes 60*60 seconds 42 miles  3600 seconds in 3600 seconds  42 miles therefore in 1 second it will be \[\frac{ 42 }{ 3600 } miles= 0.011 miles\] therefore your mps is = 0.011 miles per second

Best ResponseYou've already chosen the best response.2for minutes just divide 272 by 60 , because in each minute there are 60 seconds so 272/60= 4.533 minutes and in hours just divide 4.533 by 60 again so it will be 0.0755 hours , hope that helps you :D
