Meda arrived at work at 8:14 A.M. and Kirstin arrived at 9:12 A.M. How long had Meda been at work when Kirstin got there? a. 1 hour 8 minutes b. 1 hour 2 minutes c. 58 minutes d. 30 minutes
Answer: c. 58 minutes
Between 8:14 and 9:00, 46 minutes elapse,
and between 9:00 and 9:12, 12 minutes
elapse, so this is a simple addition problem:
46 + 12 = 58.
