For the second one, that's easy.

The diameter of the observable universe is 93,000,000,000 Light Years

C=πd

π * 93,000,000,000 = 292,168,116,784 Light Years

Simply divide that by the timeframe and time unit to find a result. I.E:

292,168,116,784 Light years / 1 Attosecond = 2.76406477 × 10^45 m/s

Note: This assumes that the Observable Universe is spherical in nature.

The first one is a bit trickier. The hardness of Steel (I presume one of the harder variants) is 1550 N/mm^2, or 1550 MPa. However, I'm not quite sure how to find the value 10 times greater then that. I feel as if simply timing that by 10 would be disingenuous, so I can't really help you there. Sorry.
