4 Review for Mastery Time and Temperature You can use the table below to convert units of time. To convert minute 0 to, find the number of in minute. Then find the total number of. minute 0 = = 70 Convert. minute. hour 5 = 2. 2 days 3 hours = hours You can find elapsed time by counting up or back. Sue started to clean her room at 8:5 A.M. She spent 40 cleaning. At what time did Sue finish? Time Started Time Spent Time Finished Solve. Time minute = 60 year = 52 weeks hour = 60 year = 2 months day = 24 hours year = 365 days week = 7 days 8:5 A.M min = 8:55 A.M. Count up Carlos started to wash the car at 3:5 P.M. He spent hour 0 washing the car. At what time did he finish? You can estimate the temperature by using the rules below. To change from C to F, double To change from F to C, subtract 30 from the temperature and then add 30. the temperature and then divide by C 0 F = = = = C is about 0 F. 0 F is about 40 C. Estimate the temperature C is about F F is about C.
5 Challenge That s So Hot! Estimate the temperatures of the following hottest places in the world. The highest temperature ever recorded on the continent of Africa was 36 F, or about C. The hottest temperature ever recorded on the continent of Antarctica was 59 F, or about C. The hottest temperature ever recorded on the continent of Asia was 29 F, or about C. The hottest temperature ever recorded on the continent of Australia was 28 F, or about C. The highest temperature ever recorded on the continent of Europe was 50 C, or about F. The hottest temperature ever recorded on the continent of North America was 57 C, or about F. The hottest temperature ever recorded on the continent of South America was 49 C, or about F.
