I go from my home to office at speed of 95km\h for 130 min and I come back at speed of 60km/h in 3 hrs 20 min.

Solution :
home to office speed = 95 km/ hr
= 95 *1000 m / 60*60 s
= 95 * 5 /18 m/s
= 475/18 m/s
time taken from home to reach office = 130 minutes
= 130 * 60 sec
=7800 s
Therefore ,
Distance from home to office = velocity * time
= 475/18 *7800
= 205833.33 m
Office to home Speed =  60 km /hr
= 60 *1000 / 60*60 m/s
= 60 *5 /18 m/s
= 300 / 18 m/s
time taken from office to home = 3hr 20 min
= 3*60*60 seconds + 20*60 seconds
=(10800 + 1200)seconds
= 1200 seconds

In Case You want to find the average velocity from home to office and back to home
Average Velocity = 2 v1 v2 / v1 +v2  (Shortcut Formula When Distances are equal )
v1= velocity from home to office
v2 = velocity from office to home
= 2*95*60 /(95+60) km/hr
=11400 /155 km/hr
= 73.54 km/hr
