Question 161125: At 9:30AM Andrew left Exeter for Portsmouth cycling at 12mph. At 10:00AM Stacy left Portsmouth for Exeter cycling at 16mph. The distance for Exeter to Portsmouth is 20miles. Find the time they met.
My thoughts- 20= 12 x T
8 = T so,....
20 = 16 x .50T
20= 16 x 4 NOPE!!!

Let's start here.
They are 20 miles apart to begin with at 9:30 AM.
Andrew starts riding at 9:30AM.
At 10:00 AM, Andrew has already moved 6 miles (12mph x 1/2hour), so then they are only 14 miles apart.
This is the distance they have to travel together to meet.
Andrew moves at and Stacy moves at to cover the 14 mile gap.

They both travel an additional 1/2 hour and meet at 10:30AM.
Andrew will have traveled 6+(12*1/2)=6+6=12 miles.
Stacy will have traveled 16(1/2)=8 miles.
