If x and y vary inversely and x = 5 when y = -3.5, what is the value of x when y = 10?

Let x = speed and y = distance

y = x * 45

y = (x - 4) * 70

45x = 70x - 280

-25x = -280

x = 11.2

Put it back into the first equation:

y = 11.2 x 45

y = 504miles

Hope this helps! Any questions let me know :)
