Distance || times (h)
7 1/2 || 1/2
15 || 1
22 1/2 || 1 1/2
30 || 2
37 1/2 || 2 1/2
If you add up all of the digits in the number, and if that number you get is able to be divided by 3, the original number is good to divide by 3.
For example: 618
You add 6+1+8 and get 15
Take 15 and divide by 3
You get a whole number, 5
Therefore, 618 can be divided by 3

Answer:
Step-by-step explanation:
Here is an illustration of the problem:
----------------------------->|<------------------
A t J
Alex and Jo start from their separate homes and drive towards one another. The t indicates the time at which they meet, which is the same time for both. Filling in a d = rt table:
d = r x t
Alex 14 t
Jo 6 t
The formula for motion is d = rt, so that means that Alex's distance is 14t and Jo's distance is 6t.
14t 6t
---------------------------------->|<------------------
A t J
The distance between them is 5 miles, so that means that Alex's distance plus Jo's distance equals 5 miles. In equation form:
14t + 6t = 5 and
20t = 5 so
t = .25 hours or 15 minutes.
If they leave their homes at 3 and they meet 15 minutes later, then they meet at 3:15.
