Ping result

[knaik99]

When we ping Host A from Host B and we are getting average ping response as 50 ms 

means on average, we can reach to Host A at 25 ms from Host B.

 Ping gives result as ICMP request + ICMP reply,Right? i.e. Round trip time (RTT)

[MHM Cisco World]

Yes, you right RTT calculate the time go and back.

[knaik99]

Do Traceroute also tell about RTT at each HOP?

[MHM Cisco World]

I make double check 
it same as ping the traceroute list the RTT for each probe

Correct - take a look at below example : (how the averate come in picture) min 4s and maximum 6 - so averate 5ms

"means on average, we can reach to Host A at 25 ms from Host B."

Incorrect.  It means Host A can communicate with Host B with an average RTT of 50 ms.  We don't know if, for example, each way might be only 20 ms, but the one direction is currently congested adding another 10 ms to current RTT.  Available bandwidth and/or paths are not always symmetrical, i.e. each direction might take a different amount of time.

"Ping gives result as ICMP request + ICMP reply,Right? i.e. Round trip time (RTT)"

Correct.

PS:

BTW, sometimes part of the RTT is "wait" time on the pinged host.  Ping was really designed, more-or-less, as quick way to determine if another host is alive, not as a precision timing tool.  (Also BTW, Cisco's SLA responder has an option to mitigate destination host "wait" time; to try to provide a more accurate RTT time.)

Do traceroute also gives at RTT time with each HOP till destination?

[MHM Cisco World]

I already answer you for this Q,
this the output of each traceroute rows 

Hop   RTT1      RTT2    RTT3     Name          [IP Address]

4      13 ms     8 ms     9 ms     MHM           [68.86.90.57]

[knaik99]

means each HOP is seen with RTT time right?

[MHM Cisco World]

Yes but not with only one RTT but three because traceroute send by default three probe (three exact same traceroute packet with same TTL value).
if one probe missing drop then it RTT will appear as " * "
