Answer:
The answer is:
11 hours+0.42 hours=11.42 hours.
Explanation:
In order to determine the answer, we have to calculate minutes and hours separately. The result of minutes has to be expressed in hours.
In hours, from 7 am to 6 pm:
7 am, 8 am, 9 am, 10 am, 11 am, 12 am, 1 pm, 2 pm, 3 pm, 4 pm, 5 pm, 6 pm.
There are 11 hours from 7 am to 6 pm.
In minutes, from 10 min to 35 min, there are 35-10=25 min
Finally, we have to convert minutes to hours. The amount of minutes is divided by 60. The number 60 is because an hour is 60 minutes.

Finally the answer is:
11 hours+0.42 hours=11.42 hours.
