Each second has 1,000 msec in it.
Multiply the number of seconds by 1,000 and you have
the number of milliseconds in the same length of time.
1000 msec = 1 sec 30,000 msec = 30 sec
3500 msec
Blink of eye is between 100 - 400 msec accordance to wikipedia.org. It is 0.1 - to 0.4 of seconds.
1000
Multiply seconds by 1,000.
ms or msec
MPH = miles per hour. In order to calculate hours from seconds, you just need to know that there are 3,600 seconds in an hour.
250 msec
Multiply by 24x60x60. This is 86400 seconds in a day.
Let t=0 denote the start of transmission. At t=1 msec, the first frame has been fully transmitted. At t=271 msec, the first frame has fully arrived. At t=272 msec, the frame acknowledging the first one has been fully sent. At t=542 msec, the acknowledementbearing frame has fully arrived. Thus, the cycle is 542 msec. A total of k frames are sent in 542 msec, for an efficiency of k/542. Hence a) k=1, efficiency=1/542=0,18% b) k=7, efficiency=7/542=1,29% c) k=4, efficiency=4/542=0,74%
