Noah solved three math problems. The first problem took him 1 minute. The second problem took him 30% longer than the first prob
lem, and the third problem took him 50% longer than the second problem. How long did it take Noah to solve all three problems?
1 answer:
60 seconds * 1.30 = 78. 78 seconds * 1.5 = 117 seconds.
117+78+60= 225 seconds.
225 seconds is your answer! :)
