Part 1: Calculate Elapsed Time Step 1 Determine the start time and end time “…she clocked in at 8:15am and clocked out at 11:45pm.” Start time = 8:15 End time = 11:45 Jobs for Montana's Graduates D25L1PP1
Part 1: Calculate Elapsed Time Step 2 Write the later time first: 11:45 - 8:15 Subtract 3:30 Answer: 3 hours, 30 minutes Jobs for Montana's Graduates D25L1PP1
Part 1: Calculate Elapsed Time What if the time runs across 12:00 and the ending hours are less than the starting hours? … she clocked in 8:15am and clocked out at 1:45pm Jobs for Montana's Graduates D25L1PP1
Part 1: Calculate Elapsed Time Step 2 Write the later time first: 1:45 - 8:15 Add 12 to the hours of the ending time (12 + 1= 13) Rewrite problem 13:45 - 8:15 Subtract 5:30 Answer: 5 hours, 30 minutes Jobs for Montana's Graduates D25L1PP1
Part 1: Calculate Elapsed Time What if the ending time has fewer minutes than the starting time? … she clocked in 8:45am and clocked out at 11:15pm Jobs for Montana's Graduates D25L1PP1
Part 1: Calculate Elapsed Time Step 2 Write the later time first: 11:15 - 8:45 Borrow 1 from the hours, and convert to 60 minutes (11 – 1 = 10) Add 60 to the minutes of the end time (60 + 15 = 75) Rewrite problem 10:75 - 8:45 Subtract 2:30 Answer: 2 hours, 30 minutes Jobs for Montana's Graduates D25L1PP1
Part 2: Multiply Elapsed Time by Hourly Wages Sara works at a local restaurant. On Saturday she clocked in at 8:15am and clocked out at 11:45pm. Sara earns $7.50 per hour. How much did Sara earn in gross wages? Elapsed time = 3 hours, 30 minutes Step 1 Convert minutes to part of an hour by dividing minutes by 60 30 / 60 = .5 Jobs for Montana's Graduates D25L1PP1
Part 2: Multiply Elapsed Time by Hourly Wages Sara works at a local restaurant. On Saturday she clocked in at 8:15am and clocked out at 11:45pm. Sara earns $7.50 per hour. How much did Sara earn in gross wages? Elapsed time = 3.5 hours Step 2 Multiple time in hours by wages 3.5 x 7.50 Gross Wages = $26.25 Jobs for Montana's Graduates D25L1PP1
