6. Aaron will run from home at y mph and walk back at x mph. how much distance does he need to travel to spend a total of t hours walking and jogging. (A) xt/y (B) (x+t)/xy (C) xyt/(x+y) (D) (x+y+t)/xy (E) (y+t)/x-t/y

Total distance,

Explanation:

It is given that,

Speed of Aaron from home is y mph and walk back at x mph. Let t is the total time he spend in walking and jogging. Let d is the distance covered.

We he moves from home to destination, time is equal to,

Similarly, when he move back to home, time taken is equal to

Total time taken is equal to :

So, the distance he speed in walking and jogging is . Hence, this is the required solution.

current flows in a wire

we need to know the time interval during which the force acts. impulse of force = momentum change
