Kwame studied for the history test for 2.5 hours. Connor studied for 1.5 hours and Lexia studied for 97 minutes. How many minutes more did Kwame and Connor study than Lexia?
Kwame = 2.5 hours * 60 minutes = <<2.5*60=150>>150 minutes
Connor = 1.5 hours * 60 minutes = <<1.5*60=90>>90 minutes
Kwame + Connor = 150 + 90 = 240 minutes
240 - 97 = <<240-97=143>>143 minutes
Kwame and Conner studied 143 minutes more than Lexia.
