Question 1121342
.
<pre>
Ivan started first, and from 8 am till 9:30 am he moved toward Kate 12 mph * 1.5 hours = 18 miles.


So, at 9:30 am the distance between them is  42 - 18 = 24 miles.


Starting from 9:30 am they BOTH move toward each other.  Their relative speed is 12 + 18 = 30 miles per hour.


So, they will cover the distance of 24 miles between them in  {{{24/30}}} = {{{4/5}}} hours, which is 48 minutes.


So, they will meet each other 48 minutes after 9:30 am,  which is  10:18 am.

Solved.
