Rhonda:
d=20+%28mil%2Fhour%29%2At..... In 24 minutes, which is 0.4 hours, she will be
d=20+%28mil%2Fhour%29%2A0.4h
d=8mil from starting point
Juan:
d=15+%28mil%2Fhour%29%2At..... In 24 minutes, which is 0.4 hours, she will be
d=15+%28mil%2Fhour%29%2A0.4h
d=6mil from starting point
since they go in opposite directions, total distance in 24 minutes is 8mil%2B6mil=14mil

From her starting point, and travelling in a certain direction, Rhonda will travel %2824%2F60%29+%2A+20, in 24 minutes
From the same starting point, and travelling in the opposite direction, Juan will travel %2824%2F60%29+%2A+15, in 24 minutes
After 24 minutes, they will travel a total of:

=======================
When moving in opposite directions, the speeds are added.
20 + 15 = 35 mi/hr
--------------
d = r*t
35*0.4 = 14 miles.

Sorry, no Master's Thesis for that.
