EXERCISE 41

(1) How many seconds are there in:

(a) 6 minutes = (6 × 60) = 360 seconds

(b) 15 minutes = (15 × 60) = 900 seconds

(d) 2 hours = (2 × 60) minutes = (120 × 60) = 7200 seconds

(e) 7 min 16 s = (7 × 60) + 16 = 420 + 16 = 436 seconds

(f) 10 min 35 s = (10 × 60) + 35 = 600 + 35 = 635 seconds

(2) How many minutes are there in:

(a) 8 hours = (8 × 60) = 480 minute

(d) 5 hours 25 min = (5 × 60) + 25 = 300 + 25 = 325 minutes

(e) 9 hours 12 minutes = (9 × 60) + 12 = 540 + 12 = 552 minutes

(3) How many minutes are there in:

(4) How many hours are there in:
