Somebody help please ASAP!

  5:30pm

Step-by-step explanation:

We assume the destination distance does not include the 35 miles already traveled, and that the travel speed remains constant.

We can set up a proportion for the travel time in hours:

  (1/2 hour)/(35 miles) = (x hours)/(245 miles)

Multiplying by 245, we find ...

  x hours = (1/2 hour) × 245/35 = 7/2 hours

It will take the family 3 1/2 more hours to reach their destination. 3:30 after 2:00 pm is 5:30 pm.

The Davis Family will arrive at 5:30 pm.
