'Calculate the delay response of following http connections: Non- persistent, non-persistant with 4 parallel connections, Persistent without pipeline

Suppose a client A requests a web resource from server B, which comprises of base page (html) that further includes 12 objects. Calculate the delay response of following http connections: Non- persistent, non-persistant with 4 parallel connections, Persistent without pipeline, persistent with pipeline. Note: a) The RTT between A&B is 600ms & transmit time for each object is 10 ms. b) The RTT between A&B is 500 ms & link connectivity is 5 mbps & each object is 50 kb.

HTTP response time = 2RTT + Transmission time. Transmission Time = Message_size/Bandwidth.

I am not getting how to use these Formulas.Been searching on google for hours.
