Answer:
[tex]140 \: mins = tex]140 \: mins = 2 hours 30minutes
[tex]750 \: mins \: = 12 hours 30 minutes
[tex]680 \: mins \: = 11 hours 20 minutes
Step-by-step explanation:
Since 60 mins = 1 hour, then
140 mins = 140 / 60 Divide both numerator and denominator by 10
= 14 / 6 Divide both numerator and denominator by 2
= 7 / 3
[tex]140 \: mins = 2 \frac{1}{2} \: hours[/tex]
[tex]140 \: mins = 2 hours 30minutes
Also,
750 mins = 750 / 60 Divide both numerator and denominator by 10
= 75 / 6 Divide both numerator and denominator by 3
= 25 / 2
[tex]750 \: mins \: = 12 \frac{1}{2} \: hours [/tex]
[tex]750 \: mins \: = 12 hours 30 minutes
Finally,
680 mins = 680 / 60 Divide both numerator and denominator by 10
= 68 / 6 Divide both numerator and denominator by 2
= 34 / 3
[tex]680 \: mins \: = 11 \frac{1}{3} \: hours[/tex]
[tex]680 \: mins \: = 11 hours 20 minutes
