4 minutes = 240 seconds. Next, 240 s + 15 s = 255 s
2 minutes = 120 seconds. Next,120 + 10 = 130 seconds
2 hour = 120 min. Next, 120 min + 30 min = 150 minutes
a) 42 days + 4 days = 46 days b) 60 months + 2 months = 62 months
7.00, 3.30, 11.00
420 minutes = 7 hours. Next, 455min - 420 min = 35 minutes. So 7 hours 35 minutes.
11.30 a.m., 12.15 p.m., 1.00 p.m., 1.45 p.m.
5.30, 12.30, 9.00
1) 365 days 2) 366 days
240 s = 4 minutes. Next, 280 s - 240 s = 40 seconds. So, 4 minutes 40 seconds.
