Speed is always relative.
250km / sec is very fast however when compared to normal everyday human things. It means that in just 1 second something has travelled 250,000 metres.
It helps to think of this relative to something else. The Earth is about 40,000km around the equator. So at this speed you could do a complete lap of our planet in 40,000 / 250 = 160 seconds (2 minutes 40 seconds). As you can see, this speed is fast.
However there are things which travel faster than this. Light travels about 1200 times as fast as this! Light could do a lap in about 0.13 seconds.
