Answer:
(3,-7)
Step-by-step explanation:
Using the algebraic rule for Rx-axis
(x,y)---->(x,-y)
(3,7)--->(3,-7)
 
        
             
        
        
        
T1 + t2 = 2h and 30min;
t1 * 600 = t2 * 400 => t2 = (3/2) * t1;
then, t1 +  (3/2) * t1 = 2h and 30min => 2t1 + 3t1 = 5h => 5*t1 = 5h => t1 = 1h => t2 = 1h and 30 min;
The distance is 2 * 1 * 600 = 1200miles;
