2009 AMC 12A Problems/Problem 1

From AoPSWiki

Problem

Kim's flight took off from Newark at 10:34 AM and landed in Miami at 1:18 PM. Both cities are in the same time zone. If her flight took h hours and m minutes, with 0 < m < 60, what is h + m?

\textbf{(A)}\ 46 \qquad \textbf{(B)}\ 47 \qquad \textbf{(C)}\ 50 \qquad \textbf{(D)}\ 53 \qquad \textbf{(E)}\ 54

Solution

There is 1 hour and 60-34 = 26 minutes between 10:34 AM and noon; and there is 1 hour and 18 minutes between noon and 1:18 PM. Hence the flight took 2 hours and 26 + 18 = 44 minutes, and h+m= 46\ \textbf{(A)}.
