Answer:
The distance between the two points is 
Step-by-step explanation:
In order to find the distance between two coordinate pairs, we can use the distance formula:

Our coordinate pairs need to be labeled accordingly, so we can use this naming system:

This assigns a name to our points:
Therefore, we can plug these into the formula and solve:

Therefore, the distance between the two points is
.
It is currently 03:00 PM, the family will reach at 03:00+4.5 = 07:30 PM
Step-by-step explanation:
We have to calculate the speed first to find the time it will take the family to complete the trip.
Given
Distance = d = 25 miles
Time = t = 1/2 hours = 0.5 hours

Now,
Distance remaining = 225 miles
Speed = 50 miles per hour

As we see that the time required to complete the journey is 4.5 hours.
It is currently 03:00 PM, the family will reach at 03:00+4.5 = 07:30 PM
