The location of four amusement park rides on a coordinate grid are as follows: 
 Ride 1 at (−3,− 4) 
 Ride 2 at  (−3,2)  
 Ride 3 at (5,2) 
 Ride 4 at (5,−4) 
 Jesse begins at Ride 1 and then walks to Ride 2, then Ride 3, and then Ride 4. Then she walks back to Ride 3. The path between each ride is a straight line. One unit on the coordinate grid equals 50 yards. What is the total distance Jesse walked?
