When running a mile during a recent track meet, Nuria was initially credited with a final time of 5 minutes, 30 seconds. Shortly after her run, officials realized that the timing mechanism malfunctioned. The stopwatch did not begin timing her until 2/7 of a minute after she began to run. If the time was otherwise correct, how long did it actually take Nuria to run the mile? Options
A) 5 minutes, 17.6 seconds	B) 5 minutes, 21.8 seconds	C) 5 minutes, 23.6 seconds	D) 5 minutes, 44.44 seconds	E) 6 minutes, 10.4 seconds
One approach:   The watch starts to work after Nuria began his running. It means the time should be greater than credited 5 minutes, 30 seconds. The only number is 5 minutes, 44.44 seconds.   Another approach:   2/7 close to 20 second when added to the 5 minutes, 30 seconds, it means it passes 5 minute 44.44 seconds   Answer: 5 minutes, 44.44 seconds
