  1. 9-5 Time and Temperature Course 1 Warm Up Problem of the Day Lesson Presentation

  2. 9-5 Time and Temperature Course 1 Warm Up Convert each measurement to feet and inches. 1.95 in. 2. 128 in. Convert each measurement to meters. 3. 406 cm 4. 24,671 mm 7 ft 11 in. 10 ft 8 in. 24.671 m 4.06 m

  3. 9-5 Time and Temperature Course 1 Problem of the Day The skateboard had rolled from the house to within 1.8 m of the street before Rick caught it. If the house is 16.9 m from the street, how far did the skateboard roll? 15.1 m

  4. 9-5 Time and Temperature Course 1

  5. 9-5 Time and Temperature Course 1 Celsius and Fahrenheit are the scales used to measure temperature. You can use these formulas to convert temperature. 9 5 5 9

  6. 9-5 Time and Temperature Course 1 Additional Example 1A: Converting Time Convert. 2 hr 5 min = _____ min 2 hours 5 minutes Think: 1 hour = 60 minutes. (2  60) minutes plus 5 minutes 125 minutes 2 hr 5 min = 125 min

  7. 9-5 Time and Temperature 1 4 195 min = 3 hr Course 1 Additional Example 1B: Converting Time Convert. 195 min = _____ hr 1 hr 60 min 195 60 Think: 1 hour = 60 minutes. = 195 min • hr Write as a mixed number.

  8. 9-5 Time and Temperature Course 1 Additional Example 1C: Converting Time Convert. 3 hr = _____ s Think: 1 hour = 60 minutes and 1 minute = 60 seconds. 60 min 1 hr 60 s 1 min = 10,800 s 3 hr • • 3 hours = 10,800 seconds

  9. 9-5 Time and Temperature Course 1 Check It Out: Example 1A Convert. 3 days 7 hr = _____ hr 3 days 7 hours Think: 1 day = 24 hours. (3  24) hours plus 7 hours 79 hours 3 days 7 hr = 79 hr

  10. 9-5 Time and Temperature 1 2 102 mo = 8 yr Course 1 Check It Out: Example 1B Convert. 102 mo = _____ yr 1 yr 12 mo 102 12 Think: 1 year = 12 months. yr = 102 mo • Write as a mixed number.

  11. 9-5 Time and Temperature Course 1 Check It Out: Example 1C Convert. 2 days = _____ min Think: 1 day = 24 hours and 1 hour = 60 minutes. 24 hr 1 day 60 min 1 hr = 2,880 min 2 days • • 2 days = 2,880 min

  12. 9-5 Time and Temperature Course 1 The time between the start of an activity and the end of an activity is called the elapsed time.

  13. 9-5 Time and Temperature Course 1 Additional Example 2A: Finding Elapsed Time Shawn was scheduled to arrive at 10:15 A.M. he was 1 hour and 55 minutes late. When did he arrive? Scheduled time: 10:15 A.M. Think: 1 hour after 10:15 A.M. is 11:15 A.M. 55 minutes after that is 12:10 P.M. Arrival time: 12:10 P.M. Shawn arrived at 12:10 P.M.

  14. 9-5 Time and Temperature Course 1 Additional Example 2B: Finding Elapsed Time Ty met his friends at 1:35 P.M. He had traveled for 2 hours and 45 minutes. At what time did Ty begin his trip? End time: 1:35 P.M. Think: 2 hours before 1:35 P.M. is 11:35 A.M. 45 minutes before that is 10:50 A.M. Begin time: 10:50 A.M. Ty began his trip at 10:50 A.M.

  15. 9-5 Time and Temperature Course 1 Check It Out: Example 2A Trent’s ferry was scheduled to arrive at 9:45 A.M. he was 1 hour and 15 minutes late. When did he arrive? Scheduled time: 9:45 A.M. Think: 1 hour after 9:45 A.M. is 10:45 A.M. 15 minutes after that is 11:00 A.M. Arrival time: 11:00 A.M. Trent’s ferry arrived at 11:00 A.M.

  16. 9-5 Time and Temperature Course 1 Check It Out: Example 2B Franco’s train arrived at 4:55 P.M. He had traveled for 3 hours and 15 minutes. At what time did Franco’s train depart? Arrival time: 4:55 P.M. Think: 3 hours before 4:55 P.M. is 1:55 P.M. 15 minutes before that is 1:40 P.M. Departure time: 1:40 P.M. Franco’s train departed at 1:40 P.M.

  17. 9-5 Time and Temperature Course 1 Additional Example 3A: Estimating Temperature Estimate the temperature. 40°C is about _____ °F. 9 5 F = • C + 32 Use the formula. 9 5 Round to 2, and 32 to 30 Use the order of operations. F = 2 • 40 + 30 F = 80 + 30 F = 110 40°C is about 110°F.

  18. 9-5 Time and Temperature Course 1 Additional Example 3B: Estimating Temperature Estimate the temperature. 70°F is about _____ °C. 5 9 C = (F – 32) Use the formula. 5 9 1 2 Round to , and 32 to 30 1 2 Use the order of operations. C = (70 - 30) 1 2 C = (40) C = 20 70°F is about 20°C.

  19. 9-5 Time and Temperature Course 1 Check It Out: Example 3 Estimate the temperature. 12°C is about _____ °F. 9 5 F = • C + 32 Use the formula. 9 5 Round to 2, and 32 to 30 Use the order of operations. F = 2 • 12 + 30 F = 24 + 30 F = 54 12°C is about 54°F.

  20. 9-5 Time and Temperature Course 1 Check It Out: Example 3B Estimate the temperature. 82°F is about _____ °C. 5 9 C = (F – 32) Use the formula. 5 9 1 2 Round to , and 32 to 30 1 2 Use the order of operations. C = (82 – 30) 1 2 C = (52) C = 26 82°F is about 26°C.
