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?
Thoughts? Step-by-step reasoning:
Kwame = 2.5 hours * 60 minutes = 150 minutes. Connor = 1.5 hours * 60 minutes = 90 minutes. Kwame + Connor = 150 + 90 = 240 minutes. 240 - 97 = 143 minutes. Kwame and Conner studied 143 minutes more than Lexia.
Thus, the answer is 143.
