Proportion: 28 is to 66 as x is to 10000

28/66 = x/10000

66x = 280000

x = 280000/66

x = 4242.424242424242 seconds

There are 60 seconds per minute:

x/60 will be minutes.. x = 70.70707070 minutes

There are 60 minutes per hours

divide by 60 again to get hours

x = 1.18 hours

(0.18 hours)(60 mins/hour) = 10.71 minutes

x = 1 hours 10.71 minutes

(0.71 minutes)(60 seconds/minute) = 42.42424242 seconds

**x = 1 hour 10 minutes 42.42 seconds**
