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
