Question

How to measure actual data transfer speeds?

Answer 1

1 to get KB/s you must first convert Mega Bytes to Kilo Bytes. Since a Mega byte is roughly 1000 Kilobytes we will multiply it by 1000. We get 25,000 Kilobytes.

2 Convert minutes into seconds. Since a minute is 60 seconds we know that 2 minutes is 120 seconds (2x60=120).

Divide Kilo Bytes by Seconds to get the rate. 25,000/120=208.3. We'll round it too 210. So now we have a rate of 210 KB/s.
