Write an equivalent time using only the smallest unit. 17. 6 days 14 h (1 point) 130h 158h 134h 144h Find the elapsed time. 18. Carol drove to her sister’s house. She drove from 6:38 to 9:45. How long did she drive? (1 point) 2h 53 min 3h 7 min 3h 53 min 4h 7 min

OpenStudy (fudgyfingers):

There are 24 hours in a day, so you can multiply the number of days by 24 hours and then add the 14 extra hours to get the answer to number 17

OpenStudy (fudgyfingers):

For number 18, you would simply subtract end time minus initial time. Does that make sense to you?

OpenStudy (scienceteen8):

not really lol

OpenStudy (fudgyfingers):

Which one are you stuck on, or is it both?

OpenStudy (scienceteen8):

both for 17, 17.6 wasnt an answer choice so thats were i got confused on n i did not understand what u said for 18

OpenStudy (fudgyfingers):

6*24= ? then add 14 to the answer you got and that will give you your answer for 17

OpenStudy (scienceteen8):

144

OpenStudy (fudgyfingers):

Right, now add the 14 hours it gives you in the question to that

OpenStudy (scienceteen8):

158

OpenStudy (fudgyfingers):

There you go! That's your answer

OpenStudy (scienceteen8):

ok

OpenStudy (fudgyfingers):

For 18, you just subtract. 9:45-6:38

OpenStudy (scienceteen8):

3.07?

OpenStudy (fudgyfingers):

Right! nice job!

OpenStudy (scienceteen8):
