You are planning a road trip and you want to calculate how long each portion of the trip will take to complete. You know the distance you will be traveling and the speed you think you will be driving for each portion of the trip. You realize that since d=rt we also know that =d/r. Fill in the missing information in the chart.

139 / 65 = 2.14 2.14 * 60 = 128.4 128.4 * 60 = 7704
7704 - (128 * 60) = 24 SEC
128 - (2 * 60) = 8 MIN

261 / 70 = 3.73 3.73 * 60 = 223.8 223.8 * 60 = 13428
13428 - (223 * 60) = 48 SEC
223 - (3 * 60) = 43 MIN

Leg 1 = 2 Hr : 8 Min : 24 Sec
Leg 2 = 3 Hr : 43 Min : 48 Sec
Leg 3 = 3 Hr : 2 Min : 24 Sec
2 + 3 + 3 = 8 HR : 8 + 43 + 2 = 53 MIN : 24 + 43 + 24 = 91 SEC
53 + 1 = 54 MIN = 1 MIN 31 SEC
Total time = 8 Hr 54 Min 31 Sec
