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
