julie arrived 20 minutes before the race began. she started right on time. it took her 24 minutes to finish the6kilometer race. she stayed 10 minutes after the race to cool off; she left. if she arrived at the race at 9:10a.m., what time was it when she left ?

20 + 24 + 10 = 54 minutes
9:10 + 54 = 10:04
