Answer 1

The arnold family arrived at the beach at 10:30 A.M.

10:30 

Add 3 hours and 3/4 minutes to that

3/4 = 75% of 60

.75 * 60 = 45

3 hours and 45 minutes 

10:30 >> 3 hours more = 1:30
1:30 + 45 mins = 2:15

Answer would be: They left at 2:15

Answer 2

In order to answer this you first will add 3 hours to 10:30, this is 1:30. Then you need to know what 3/4 of an hour is. An hour is 60 minutes so you just break it into 4 parts, that is 15 minutes per part. so 15 times 2 equal 45 minutes. You add that to 1:30 and get 2:15. That means the arnold family left the beach at 2:15 pm.
