Each person shakes 7 hands, but once you count the handshake between A and B, you don't need to count the handshake between B and A. There are a total of 8*7/2 = 28 handshakes.
We can rewrite the given time as:
- 7.03x10^15 mins
- 1.17x10^14 hours.
- 4.88x10^12 days.

What is 4.22x10^17 seconds in minutes and hours?</h3>
First, remember that:
60s = 1 min
Then to write that amount in minutes, we just need to divide by 60, so we get:
(4.22x10^17)/60 mins= 7.03x10^15 mins
Now, remember that:
1 hour = 3600s
Then to get the time in hours, we need to divide by 3600:
(4.22x10^17)/3600 h = 1.17x10^14 hours.
Similarly, you can change to any time unit that you want, for example:
1 day = 24*3600 s
Then the time in days is:
(4.22x10^17)/(24*3600) days = 4.88x10^12 days.
And so on.
