Time dilation reduces speed

Example:
An object moving with 200000km/sec covers 100000000km in 500 seconds
if there is no time dilation. If there is time dilation, a gamma value
of sqrt(1-vv/cc) = .7453 applies and the 500 seconds at rest dilate
into 500secs/.7453 = 670.82 seconds. An extra 170.82 seconds has been
generated and the object will cover the same 100000000km in 670.82
seconds at a reduced speed of 149071km/hr. The speed is reduced as the
relationship between distance, time and speed cannot be violated. With
or without time dilation, the spaceship will cover a distance of
100000000km or any other distance in the same time.
