Accepted Answer

(a) 1 hr = 60 min2 hr = 2 × 60 = 120 min4 hr = 4 × 60 = 240 min7 hr = 7 × 60 = 420 min480 min = 8 hrAs, 8 hr = 8 × 60 = 480 min9 hr = 9 × 60 = 540 min660 min = 11 hrAs, 11 hr = 11 × 60 = 660 min720 min = 12 hrAs, 12 hr = 12 × 60 = 720 m(b) Do as instructed. You can use the above double number line for the following ‘ conversions.Solution:(i) 1 hr 10 min = 60 min + 10 min = 70 minSo, 1 hour 10 minutes = 70 minutes.(ii) 2 hr 45 min = 120 min + 45 min = 165 minSo, 2 hours 45 minutes = 165 minutes,(iii) 3 hr 15 min = 3 times 60 + 15 min – 180 min + 15 min = 195 minSo, 3 hours 15 minutes = 195 minutes.(iv) 4 hr 20 min = 4 times 60 + 20 min= 240 min + 20 min = 260 minSo, 4 hours 20 minutes = 260 minutes.(v) 75 min = 60 min + 15 min = 1 hr 15 minSo, 75 minutes = 1 hour 15 minutes.(vi) 150 min = 120 min + 30 min = 2 hr 30 minSo, 150 minutes = 2 hours 30 minutes.(vii) 220 min = 120 min + 60 min + 40 min = 2 hr + 1 hr + 40 min = 3 hr 40 minSo, 220 minutes = 3 hours 40 minutes.(viii) 390 min = 240 min + 120 min + 30 Mn = 4 hr + 2 hr + 30 min = 6 hr + 30 minSo, 390 minutes = 6 hours 30 minutes(c) Fill in the blanks in the double number line to complete the conversions.Solution:120 sec = 2 min, as 2 min = 2 × 60 = 120 sec.Multiplying by 5 to the previous marking we get the number for the next marking on the number line for minutes. To get the corresponding seconds on the seconds number line we need to multiply the number of minutes by 60.(i) 320 sec = 300 sec + 20 sec = 5 min + 20 secSo, 320 sec = 5 min 20 sec(ii) 225 sec = 120 sec + 60 sec + 45 sec= 2 min + 1 min + 45 secSo, 225 sec = 3 min 45 sec(iii) 700 sec = 600 sec + 60 sec + 40 sec= 10 min + 1 min + 40 secSo, 700 sec = 11 min 40 sec(iv) 1000 sec = 900 sec + 60 sec + 40 sec= 15 min + 1 min + 40 secSo, 1000 sec = 16 min 40 sec(v) 10 min 13 sec = 600 sec + 13 sec= 613 secSo, 10 sec 13 sec = 613 sec(vi) 4 min 8 sec = 2 min + 2 min + 8 sec= 120 sec + 120 sec + 8 sec = 248 secSo, 4 min 8 sec = 248 sec(vii) 15 min 40 sec = 900 sec + 40 sec= 940 secSo, 15 min 40 sec = 940 sec
