julie arrived 20 minutes before the race began. she started right on time. it took her 24 minutes to finish the6-kilometer 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
To find out what time Julie left the race, we need to add up the time it took her to finish the race and the time she stayed after the race.
First, let's break down the given information:
- Julie arrived at the race 20 minutes before it began.
- The race took her 24 minutes to finish.
- She stayed 10 minutes after the race to cool off.
So, Julie spent a total of (20 + 24 + 10) = 54 minutes for the race and cooling off.
To calculate the time she left, we'll add 54 minutes to the time she arrived:
9:10 a.m. + 54 minutes = 10:04 a.m.
Therefore, Julie left the race at 10:04 a.m.
