Answer:

Average speed = \frac{(x+y)}{2} miles per hour

Step-by-step explanation:

Formula to calculate the average speed of an object is,

Average speed = \frac{\text{Total distance covered}}{\text{Time taken to cover this distance}}

If I travel with the speed of x mph for t hours,

Total distance covered = Speed × Time

                                       = x\times t

                                       = xt miles

Similarly, if I travel with the speed y mph for t hours,

Total distance covered = yt miles

Total distance covered by me = (xt+yt) miles

Total time taken to cover this distance = t+t

                                                                 = 2t hours

Therefore, expression for the average speed will be,

Average speed = \frac{xt+yt}{2t}

                          = \frac{(x+y)t}{2t}

                          = \frac{x+y}{2} miles per hour

The answer :

4/5

Step-by-step explanation:

4x-5y=0  

subtract 4x on both the sides  

4x-4x-5y = 0-4x  

-5y = -4x

divide by -5 on both the sides  

-5y/-5 = -4x/-5

y =( 4/5 )x
