Answer:

They will meet at 5:00 PM

Step-by-step explanation:

Speed =\frac{Distance}{Time}

\implies Distance = Speed\times time

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

45t + 60(t-3) = 345

105t - 180 = 345

105t = 525

t=\frac{525}{105}=5

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