60s, 120s, 180s, 240s, 300s
2 minutes = 120 seconds. Next,120 + 10 = 130 seconds
4 minutes = 240 seconds. Next, 240 s + 15 s = 255 s
240 s = 4 minutes. Next, 280 s - 240 s = 40 seconds. So, 4 minutes 40 seconds.
60 min, 120 min, 180 min, 240 min, 300 min
2 hour = 120 min. Next, 120 min + 30 min = 150 minutes
420 minutes = 7 hours. Next, 455min - 420 min = 35 minutes. So 7 hours 35 minutes.
