To find the speed of an electromagnetic wave in a medium, we can use the formula:

v = 1 / √(εr * μr)

Given that εr = 1 and μr = 1, we can substitute these values into the formula:

v = 1 / √(1 * 1)

Simplifying the expression:

v = 1 / √1

Since the square root of 1 is 1, we have:

v = 1 / 1

Therefore, the speed of the electromagnetic wave in this medium is 1.
