You simply need to devide the distance by the speed to get the time, so: 600÷50= 12hrs
This is only if you drive the same speed rhe whole way and do not stop. If you stopped you need to add the delay to the time.
For example: if you delayed 20 min altogether you need to add 12:00+00:20= 12:20.
        
             
        
        
        
Commutative property of multiplication is two numbers being multiplied either way,example 1x2 = 2x1.
