9 How much 3 hours 12 minutes is more than 1 hour 40 minutes?

Answer»

Difference between 3 hrs 12 minutes and 1 hr 40 minutes

3 hrs 12 min = 3 + 12/60= 3 + 1/5 = 16/5

1 hr 40 min = 1 + 40/60= 1 + 2/3 = 5/3

Then, 16/5 - 5/3 =( 48 - 25)15= 23/15 hrs= (23/15) *60 min= 23*4 = 92 min

Therefore 3 hr 12 min more than 1 hr 40 min by 92 min or 1 hr 32 min
