Total time= 7.5hr
Case I from Vijayawada to Kodada
Time'= 3hrs
Speed'=60kmph
Distance'(d')= Speed*Time
= 60*3
=180km
Case II from Kodada to Hyderabad
Time"=4hrs
Speed"=80kmph
Distance"(d")=Speed*Time
=80*4
=320km
Total Distance= d' + d"
= 180+320 km
= 500km
Average Speed = Total Distance/ Total Time
= 420/7.5
= 56 km/h
