I know for a fact that the Airjet Express had shorter flight times because it had lesser dots than the Cross Country Airlines. Hope this helped!
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
Your answer would be, A. <span>3√ 2. Hope I helped you :)</span>
