Answer:
They will meet at 5:00 PM
Step-by-step explanation:


Let Patty takes t hours to meet Toby,
Patty's speed = 60 miles/h
So, the distance covered by Patty = 60t miles,
Patty leaves at noon and Toby leaves at 3:00 pm with speed of 60 mi/h,
So, the time taken by Toby = (t-3) hours,
Thus, the distance covered by Toby = 60(t-3) miles
When they meet,
Distance covered by patty + Distance covered by Toby = total distance them




Hence, they meet 5 hours after 12:00 PM i.e. 5:00 PM.
