Question 67532
We'll determine how many hours it takes John to catch up and then add that to 11:00am-------------that will give us the answer

When the distances that both Martina and John have travelled are the same, then John will have caught up.

distance (d)=rate(r) times time(t)

d=rt 
let t= time that has elapsed since John started
then (t+2) Martina's elapsed time


Martina's Distance=24mph(t+2)

Johns Distance=48t

When the distances that both Martina and John have travelled are the same, then John will have caught up.
24(t+2)=48t
24t+48=48t   subtract 24t from both sides:
48=24t
t=2 hours-----------------'till they are both at the same place

11:00am+2 hours=1:00pm------------------------the answer we are looking for

CK
Martina's Distance=24mph(t+2)=24(4)=96 mi

Johns Distance=48t=48(2)=96 mi
