swissgirl · Answer

ok so we have 9.5 hrs practised all in all in 3 days so lets divide 9.5 by 3
9.5 hrs practiced\3 days
hmm i am getting an ugly number which is 3.166666667 which is 19/6

swissgirl · Answer

19/6 can be changed to 3 hrs and 20 minutes
So on average of 3 hours and 20 minutes are practiced every day

The answer I came up with was also 3.16666666, but the choices are: 
A 3hrs B 3hrs 6min C 3hrs 10min D 4hrs

swissgirl · Answer

its 3 hrs and 10 minutes

swissgirl · Answer

Like  the answer was 3.16666666 so we know what 3 is but we dont know what .166666667 of an hr is. so I multiplied .166666667*60=10 so its 10 minutes
So our answer is 3 hours and 10 minutes
