Add 2 hr 40 min 32 sec and 4 hr 28 min 38 sec
kvnmurty:
Add seconds values first. 32 + 38 = 70 sec. More than 60 sec. or 1 minute. So convert it into minutes & seconds = 1 minute and 10 seconds. Add 1 to the sum of minutes. So total minutes = 40 + 28 + 1 = 69 min. As it is more than 60, convert it into hours and minutes. we get 1 hour and 9 minutes. So add 1 to the sum of hour values. Hours total = 2 + 4 + 1 = 7 hours.
So the total sum = 7 hours , 9 minutes and 10 seconds.
