What 3 divided into 4 hours and 30 minutes?

Answer 1

4 hr 30 min ÷ 3 = 1 hr 30 min

Either work directly, remembering 1 hr = 60 mins:

4 hr ÷ 3 = 1 hr remainder 1 hr

1 hr + 30 min = 60 min + 30 min = 90 min

90 min ÷ 3 = 30 min

⇒ 1 hr 30 min

Or, convert to minutes, do the calculation and convert back:

1 hr = 60 min

⇒ 4 hr 30 min = 4 x 60 min + 30 min

= 270 min

270 min ÷ 3 = 90 min

60 min = 1 hr

⇒ 90 min = 90 ÷ 60 hr

= 1 hr 30 min

Alternatively working in hours:

30 min = 30 ÷ 60 hr = 0.5 hr

⇒ 4 hr 30 min = 4 hr + 0.5 hr = 4.5 hr

4.5 hr ÷ 3 = 1.5 hr = 1 hr + 0.5 hr

= 1 hr + 0.5 x 60 min

= 1 hr 30 min
