4 hours 30 minutes = ? Minutes

tigry1 [53]

The answer is: " 270 minutes " .
__________________________________________________________
→ There are "270 minutes" in "4 hours and 30 minutes" .
__________________________________________________________
Explanation:
__________________________________________________________
Method 1):
__________________________________________________________
Note: 60 minutes = 1 hour (exactly);

30 minutes = ? hr ? ;

→ (30 minutes) * (1 hr/ 60 minutes) ;

= (30/60) hr = (3/6) hr = (3÷3)/(6÷3) hr ;

= " $\frac{1}{2}$ hr " ;

or; write as: " 0.5 hr " .
_________________________________________________________

So "4 hours & 30 minutes" = 4 hours + 0.5 hours = 4.5 hours.

→ 4.5 hours = ? minutes ;

The answer is: " 270 minutes" . 4.5 hours * $\frac{60 min}{1 hr}$ ;

= (4.5 * 60) minutes = " 270 minutes " .

→ The answer is: " 270 minutes ".
___________________________________________________________
Method 2)
___________________________________________________________

"4 hours and 30 minutes" =  ?  minutes " .
___________________________________________________________

→ " 4 hours =  ?  minutes " ;

→ 4 hr . * $\frac{60 min}{1 hr}$ = (4 * 60) minutes = 240 min. ;

→ There are " 240 minutes in 4 hours" .

→ To find the number of "minutes" in "4 hours and 30 minutes" ;

→ we takes the number of minutes in 4 hours—which is "240 minutes"—and add "30 minutes" to that number; as follows:

→ " 240 minutes + 30 minutes " ;

to get: " 270 minutes " .
_______________________________________________________

 → There are "270 minutes" in "4 hours and 30 minutes" .
_______________________________________________________

The answer is: " 270 minutes " .
